See Example 7, Calculating Annual Growth Rates for Bed Tax Revenues, for one way to
calculate average growth rate.
Attraction 1 has more overall visitors than Attraction 2, but the growth rate in visitation for Attraction 2 is much higher. It might be worth spending time finding out what strategies Attraction 2 is using to sustain such fast growth and to find out what Attraction 1 is doing that may be leading to lower growth rates. The difference in growth may reflect changes in visitor preferences, or in what visitors are interested in doing. The question then becomes, can Attraction 1 do anything to appeal to this change in preferences. Remember growth rates can be deceptive when you compare an attraction that started with very low visitation and then increased, to one with high visitation all along. As the level of visitation grows, the growth rate can be expected to decrease.
d. Event Related Figures
Events that are held in enclosed areas and require admission are the easiest to monitor. Use of event locations with limited entrances and exits (such as fair and rodeo grounds) might be encouraged even when admission is not charged in order to keep better track of the number of visitors. When this is not possible, due to the nature of the event or the purpose of the event, then it may be necessary to use other sources of information to estimate attendance. These include estimates by police of crowd size and estimates by volunteers with hand held counters stationed at key entry or exit areas and traffic counts. You may be able to supplement some of this information with data on raffle ticket sales or soft drink sales.
Check with the city or town transportation division to see if road counters are in place in the area where the event is to be held. If they are, the difference between the average counts for a particular day of the week and the actual count for the day of the event should help in estimating approximate attendance at the event. How effective road counters are will depend on the number of vehicle access points to the event and the placement of the counters. It may be possible to request that a road counter be installed at the access point to parking just for the event as a means of estimating attendance.
Another way to estimate attendance for events where there is no admission fee, is to rely on crowd estimates by police officers. Find out from the local police what kind of training they have had in estimating crowds, and when they will be making their estimates. For some events, people may be spending the whole day, for others, they may just be visiting a few hours. Hence, if the amount of turnover in visitors is not known it may be difficult to estimate total attendance based on periodic police crowd estimates.
If there are a limited number of entrances into the event and you have a large group of volunteers helping you, you could have volunteers at the entrances with hand counters keeping track of the number of people coming into the event area. Of course, some people may come in and out of the event area more than once during their visit. As mentioned earlier, keeping track of the number of soft drinks sold or the number of individual sales of raffle tickets (not just the number of tickets sold) can be other ways of estimating attendance at an event. Since not everyone at an event will buy a soft drink or raffle tickets, and others will buy more than one, these counts generally provide only rough estimates of attendance.
At this point, you may be convinced that charging some sort of entrance fee to events makes sense not only as a way of raising money to support the event, but also as a way of keeping track of attendance. At some events, people who pay admission get a discount off of one or more purchases that they make at the event to help offset their admission fee. In other events, each paid admission is awarded a raffle ticket. This may help ease the pain of having to pay for admission.
In some instances, you may just want to do periodic car counts to get an estimate of visitation to the community. License plate counts can be particularly useful in communities with a high level of out-of-state visitors, but may not be so useful if most of your visitors are from in-state. You will also not be counting out-of-state and foreign visitors who rented a car with in-state plates and drove to your community.
In a car or license plate survey, you can randomly select times and dates to send volunteers to main entries into the community to count the number and type of license plates they see. On streets with more than two lanes, a volunteer might monitor one lane for half of the period and the other lane for the other half of the period. If visitation to your community is concentrated on particular days or times of the year, you may just want to monitor license plates during these peak times. Volunteers should monitor both the number of in-state and out-of-state license plates that they see to help in estimating out-of-state licensed cars as a percent of the total. Visitor counts can also be derived by counting the number of designated parking spaces and then monitoring their occupancy during the day.
e. Visitor Information From Visitor Centers
Many local Chambers of Commerce, Convention and Visitor Bureaus, and Tourism Authorities maintain visitor centers to provide information to tourists. Keeping counts of people who stop for information is another good source of visitor numbers. There is typically no admission fee to enter a visitor center, so door counters and registration books are used to keep track of visitors.
A registration book can be used effectively to collect more information than where the visitor is from. You can also set up the registration to ask a few simple questions, such as how many nights visitors are staying in the community and how many people are in their visitor party. Appendix A contains some examples of registration forms.
Keep in mind that generally only a portion of total visitors stop at a visitor center and their characteristics may not be typical of all visitors. In the Globe-Miami study, 15 percent of all visitors stopped at a visitor center. In the Tucson study, 3 percent of visitors staying in commercial accommodations stopped at a visitor center. Appendix B compares some characteristics of visitors who stopped at a visitor center in Globe-Miami and Tucson to all visitors to those communities.
f. Cost Information from Visitor Centers and Promotions
It can be exciting tracking visitor revenues, but many people who work in tourism are less excited about tracking the costs of tourism. Some of the indirect costs like congestion and increases in living costs are difficult to document. However, direct costs for visitor centers and tourism promotion are relatively easy to track. Visitor center costs can be broken out and tracked as a separate expenditure in your organization's budget. Be sure to include time spent by staff on serving visitors in this amount. If all bed tax revenues are earmarked for tourism development and promotion, then these expenditures can also be documented and shared with local leaders and citizens. In addition, if there are events held primarily for out-of-town visitors, the revenues and costs of these events can be tracked. If the costs are consistently greater than the revenues, it may be time to evaluate whether the event should continue.
Often you hear tourism promoters claim that for each dollar in tourism promotion, they generate X dollars in tourist expenditure. The most common way they reach this amount is by dividing total tourist expenditures by the amount spent on promotion. While their claims are not completely accurate, the ratio of tourist expenditures to promotion expenditures is worth tracking over time.
The promoters claims are not completely accurate because factors other than traditional tourism promotion affect visitors' decisions about how much to spend. For example, the creation of new shopping areas, new attractions, and new events can increase expenditures even if promotional expenditures stay the same. Likewise, the quality of customer service and of visitor facilities such as lodging and restaurants can affect the number of visitors and their expenditures. The ratio of promotional costs to visitors' expenditures can be used to track changes over time and to compare relative to other communities.
The ratio is not a measure of either the average or marginal impact of promotion. To measure expenditure changes caused by promotion is more difficult. It requires taking into account changes in the availability and quality of visitor facilities and attractions, and changes in customer service, inflation, and general economic conditions affecting tourism and travel.
Example 5. Estimating Total Visitor Expenditures to Costs of Promotion Using Visitor Center Cost Data.
Let's say that total tourist expenditures in your community are $2,000,000. The budget for the visitor center and all promotions last year was $100,000. Therefore, the ratio of visitor expenditures to promotion costs is $2,000,000/$100,000 = 20. The following year, let's say that tourist expenditures were $1,800,000 and promotion costs were $100,000. The ratio now falls to 18. This may be due to a single poor tourism season or it may be due to ineffective use of the promotion funds. If the trend continues, it should be of concern.
Alternatively, let's say that you receive an extra $20,000 for a special promotion campaign. During the year, visitor expenditures increase from $2,000,000 to $2,500,000. Dividing the increase in visitor expenditures ($2,500,000 - $2,000,000) of $500,000 by the increase in promotional costs of $20,000 we get a ratio of 25. Since this is higher than the ratio of 20 for all visitor expenditures to promotion costs, you have an indication that the new campaign was successful. However, other factors unrelated to the promotion may have caused the increase in visitor expenditures. If the increase in expenditures was only $250,000, the ratio would be $250,000/$20,000 = 12.5. Even though the promotion may have increased expenditures, its visitor expenditures to promotion cost ratio is lower than that of your overall tourism program. You might judge such a promotion to be unsuccessful. If you consistently find that additional promotion is not generating as high a ratio as your existing total program, this may indicate that you are already spending enough or too much on tourism promotion (or it may indicate that the special event or attraction being promoted is not as attractive in drawing visitors as other attractions). However, if the ratio is consistently quite large for additional promotion campaigns, it may indicate that more money could be well spent on tourism promotion. The difference in the ratios for a single additional promotion, however, may also simply reflect the difference in quality and effectiveness of the additional promotion compared to your other ongoing promotion efforts.
Although tracking total visitor expenditures to promotion costs is a helpful indicator, local government officials are going to be much more interested in knowing if the revenue generated by visitors is covering the public cost of serving customers. While it may be difficult to account for the use of public infrastructure such as roads and parks by visitors, costs for promotion should be readily available. Where possible, it is worthwhile to estimate additional costs for police service, search and rescue operations, maintenance of public parks and facilities, solid waste disposal from public receptacles, and road maintenance. Estimating these costs may require discussions with local service providers to identify total costs and visitors' contributions to those costs. The government revenues from visitors comes directly from taxes they pay and also indirectly from a portion of taxes paid by local residents who earn some of their income from tourism. Using bed tax information, you can come up with a rough measure of direct revenues. Estimating the indirect portion requires the estimation of economic impacts and of revenue impacts which are discussed in the two Western Rural Development Center bulletins authored by Goldman, Nakazawa and Taylor listed in the references.
Example 6. Estimating Direct Revenues and Direct Costs from Tourism.
Let's say the annual costs for tourism promotion and operation of the visitor center plus other local public service costs are $250,000. This community has a 2 percent bed tax and collected $80,000 in bed tax revenues. This means that there were $4,000,000 in lodging expenditures in the community. Let's say that a recent survey tells us that 22 percent of visitor expenditures are on lodging. So the estimated total expenditures of visitors is $4,000,000/.22 = $18,200,000. The same survey shows that 61 percent of all visitor expenditures are on taxable retail items (i.e., groceries are not included). Visitors spent a total of $18,200,000 x .61 = $11,100,000 on taxable retail items. If the city retail tax is also 2 percent, then retail tax revenues from tourists would be $11,100,000 x .02 = $222,000. Total direct revenues from tourists are $222,000 + $80,000 = $302,000. In this case, direct revenues more than cover the direct promotion costs of $250,000. The ratio of revenues to costs is then $302,000/$250,000 = 1.2.
g. Studies From Other Communities
Characteristics of visitors and their level of expenditures can vary significantly between communities. Unfortunately, visitor surveys can be expensive to do and are frequently only conducted in larger metropolitan areas and in heavily visited regions. You can still benefit from the information that you find in studies that have been done at the state, regional, county, and metropolitan area level and studies of other communities.
Generally, you will have ideas about what type of visitor you want to attract. Pay particular attention to studies that provide information on a type of visitor who is desired in your community. Studies that provide information on visitors based on their activities or interests can also be very helpful. If you want to attract more eco- or nature tourists to your community, examine the characteristics of these types of visitors from studies of other areas.
You can learn many different things from these studies. For example, they can tell you about the typical age, education and income of these types of visitors. Are you dealing with retirees or twenty-somethings? You can learn, on average, how much these visitors spend and how long they stay. Are they coming on day trips or are they overnight visitors? Do they stay in hotels, camp, or stay with family and friends? You may learn what else they are interested in doing and where else they have been on their trip. Is this a single purpose, single destination trip or a multiple destination, multiple purpose trip? What else you learn will depend on the specific questions asked in the study you are reviewing.
You can use visitor study information in many different ways in tourism promotion, development, event planning, and attraction planning. In promotion, the information can help you decide where and when to advertise. For example, knowing that most visitors are from neighboring large cities and vacation in the summer in other towns like yours, may make you decide to spend most of your advertising budget in the those cities during the summer. Visitor study results can also help guide tourism development. For example, if you want to attract birders and you have great birding resources but very few hotel rooms, you have a development problem. Serious birders watch birds in the early morning and late afternoon. They like to stay in lodging near where they plan to watch birds. To capture a share of this type of tourism will require developing more commercial lodging in your community. Visitor study information can help you design events to attract the kind of visitors that you want. For example, many baby boomers are interested in hands-on activities. If you are interested in attracting baby boomers, your festival may focus on activities that people can do at the festival. In developing or maintaining attractions, visitor study information can be used to guide projects. For example, if a study at a similar attraction was highly critical of food services, you might want to evaluate the quality of food services at your attraction.
h. State and National Studies and Data
National level studies can reveal general trends over time that will affect tourism in your community. Examples of such trends include: the tendency for people today to take more frequent trips over the year, staying closer to home and for shorter time periods, rather than taking one long vacation; the growing importance of baby boomers as tourists and their interest in hands-on experiences rather than more passive activities such as viewing museum displays; the growth in demand for "ecological" vacations, cultural tourism, and farm/ranch recreation.
Example 7. Calculating Location Quotients for Tourism Related Sectors.
You can estimate location quotients for your county very easily. Typically, such quotients are based on employment figures. A location quotient shows you how similar the distribution of employment in your county is to the state or the national distribution. Let's say that 150 jobs out of the 1,000 jobs in your county are in retail trade. This means that 150/1,000 x 100 percent = 15 percent of all employment in your county is in retail trade. If you calculate for the state, 10 percent of all employment is in retail trade. If you take the ratio of these percentages: 15/10 = 1.5 you get a location quotient that tells you that employment in retail trade in your county is 50 percent higher (or one and a half times that of) state employment in retail trade. This indicates that your economy is more concentrated in retail trade than the economy of the state as a whole.
VII. Deciding Whether Additional Data Collection Is Needed
As tourism activity grows in your community, you may reach a point where it is critical to do a more intensive study of tourism. Generally, there may be a need to undertake a study under the following circumstances:
In some instances, you may be able to find or buy high quality information collected as part of ongoing state or national surveys such as Travelscope, Travel Industry Association special surveys, or national surveys conducted by national tourism consultants. This is especially true if you are trying to target a specific niche market, such as eco-tourism. In other instances, especially when you want detailed information about expenditures and characteristics of visitors to your community, you will have to conduct a study or commission one to be done. In a companion piece to this bulletin called "A Guide to Designing and Conducting Visitor Surveys," the process of actually doing a survey is described in detail (see references).
However, the first step is always to determine that such a survey is absolutely necessary. Surveys are expensive to conduct in both time and money and should not be started casually. The advantage of doing a survey every five or ten years, is that it is possible to estimate changes in tourism expenditures between surveys if the study is tied to figures such as bed tax revenues and hotel occupancy rates.
VIII. Using Data to Track Tourism Activity Over Time
At a minimum, you should track tax revenues, hotel occupancy, and visitor counts at major attractions over time. You may want to examine this information on a seasonal or quarterly basis and write a short press release on the state of tourism in your community for that period of time. An example of a short report is provided in Appendix F.
IX. Using Data for Strategic Decision Making
One of the best starting points for strategic planning in tourism in a community is to focus on what type of visitors you want to attract to your community given the resources that you have. The Western Rural Development Center has published a handbook called "Community Tourism Assessment Handbook" (see references) that is a good starting point for a community that is planning a major development initiative in tourism, or that wants to examine how viable tourism is as a development option for their community.
Take time to assess current tourism activities in your community. What has been the cost/benefit of tourism to the community? What kind of pay back are you getting for the time and resources you are now investing in tourism development? What is the ratio of total tourism expenditures to total direct expenditures on tourism related activities? No community wants to promote tourism if it doesn't pay-if it creates more costs than benefits.
Plan time at least annually to evaluate your tourism development and marketing program, how you are now doing business. Utilize the data you've collected, as suggested in this bulletin, to assess the impact of tourism on the community. Use this data to make strategic choices toward strengthening your visitor attractions, events, and marketing. What actions could be taken to increase the level of expenditures made by visitors to your community?
We know from numerous studies that the money spent by tourists occurs largely in the community where the visitor spends the night. Visitors that stay overnight in your community in commercial accommodations spend more money per person, per party, and per trip than visitors who do not. This is not only because of their lodging expense, but also because these visitors are more likely to eat out in local restaurants and typically spend more time in local shops.
What percent of your current visitors are staying overnight in the community? How could that number be increased? Are your eating and lodging facilities memorable? What could be done to make an overnight stay in your community more appealing? If your community is a gateway to other area attractions, what can be done to insure that visitors return to your community for the evening rather than spend the night somewhere else? Strategies you might consider are guided tours, evening seminars or special entertainment, a self-guide for evening walks, unique lodging decor, added service, unique food items on local menus, retail shops open in the evening, a free community memento, special evening events at your visitor attractions, and a list of evening and weekend activities available in your community (e.g. calf roping, little league sports, dances, movies, window shopping, star gazing, early morning bird watching). Emphasize your community's overnight amenities in any promotional materials. If most visitors to your community are currently day trippers, you may be footing much of the cost of tourism without receiving the benefits.
Those visitors who are now spending the night in commercial lodging in your community and those visitors who are repeat visitors are the ones you especially want to keep happy. Listen to them closely when they have concerns or suggestions. Communities that fail to develop local accommodations and evening attractions will be continually frustrated by the low returns they get from tourism. Communities that are successful at bringing visitors back to their community are building a strong customer base.
Survey data show that the more time visitors spend in your community, the more money they spend. Are your current community attractions strong enough to hold people for a half a day, for a full day, for an overnight? What can be done to extend the amount of time visitors spend in each of your attractions? How attractive are local shopping facilities? Do you have unique tourist-oriented products for sale? Local cash registers will ring only if visitors are provided unique and rewarding ways to spend their money.
Some studies show that return visitors spend more than first-time visitors. In addition, the amount of time and money needed to attract repeat visitors is less than that required to attract a first-time visitor. Repeat visitors are also a good source of word-of-mouth advertising. Communities need to diligently work at turning current visitors into return visitors. Successful attractions target previous visitors in their marketing program.
As indicated earlier, today's visitors are taking frequent, shorter vacations, closer to home. Nationwide, short vacations presently account for 80% of vacation travel. Average length of trip is 2 to 4 days, often including a weekend. Average distance traveled is 75 to 100 miles. Consider putting together and marketing a special weekend/overnight get-away package to your community targeted to in-state residents.
Trends further indicate that today's visitors are increasingly experience seekers and are no longer content to be mere sight-seers. This is particularly true for the aging 'baby boomer' that will dominate the tourist market in the next decade. Such travelers want unique, authentic, life enriching experiences. They want to be involved. They want to learn about things. Historic experiences are increasingly popular. Ecological vacations are the fastest growing visitor segment today. This includes agriculture as well as outdoor adventure. Unique, ethnic, and gourmet food items are sought. These experience seekers tend to stay in the community longer and spend more. What can be done to incorporate experiential activities into your current attractions?
Are your visitor attractions self-sustaining, i.e. generating enough visitor revenue to cover costs of operation? If they are not, reassess the fees charged and/or improve the quality of the attraction.
Is your public infrastructure (streets, water, sidewalks, parks, directional signage, visitor information, public restrooms, etc.) adequate to host visitors? Is your community attractive and inviting to visitors? Are inadequate restrooms forcing visitors to shorten their stay in your community? Are tax revenues generated by visitors adequate to service the public infrastructure they demand?
Who benefits economically from the special events your community now hosts? Are adequate revenues generated through ticket sales, space rentals, commissions, business subscriptions, etc. to return a profit to the hosting organization? If not, how can that be changed? What percent of your food and other vendors are local residents/businesses that pay local sales tax versus out-of-town vendors? What percent of your event visitors are staying overnight in your community? Are sales and bed tax revenues generated by the special event sufficient to cover the public costs of the event (police services, garbage collection, rest rooms, litter clean-up, etc.)? Many communities routinely host special events without assessing how those events might be redesigned to increase revenue to the community. Consider targeting your event to higher value customers through for-fee special tours, seminars, and small group experiential activities.
Use the data available to you in your planning efforts. If admission at key attractions is down, include finding out why as a project in the next year. If the community is having trouble attracting new motels, and thus increasing (or replacing obsolete) rooms available, make finding out why a key objective in your strategic plan. If you identify a specific target market for promotional purposes, search out as much existing information as you can find on this market. Ask tough questions. Does your community have a high value experience to offer this market? If not, what must you do to improve your product? If you do have the product, how do you reach your target market?
Visitor surveys indicate that 'word of mouth' is the primary way visitors find out about community attractions. The best way to get good word of mouth advertising is to offer current visitors a quality experience and outstanding customer service. Travelers are becoming much more discriminating when they travel. They often rely heavily on travel guides that tell them not only what is available in a community, but provide a rating of the quality. Communities need to diligently work at turning current visitors into tourism ambassadors for the community.
X. Getting Feedback to Improve the Quality of Your Attractions and Visitor Experience
Many businesses are very concerned about how satisfied their customers are with their product or service and will provide ways for their customers to provide this feedback. You may want to find out which tourism and travel related businesses are doing this already and what they have learned. If you find that few businesses are doing this, you might want to provide training in getting customer feedback to local businesses and to attraction managers.
There are a variety of ways to get this information. They include using community swaps, focus groups, and short surveys. A community swap involves inviting groups of people who work in tourism and travel related businesses from a community of similar size as yours (and hopefully with similar levels of tourism activity as your community) to come spend a few days in your community assessing your attractions and facilities. Usually in such a swap, you send a group of people from your community to their community to do the same thing. You ask the group to share their observations and recommendations for improving services and amenities in your community. It helps if you prepare a check list and set of questions that you want your community swap visitors to use as a basis for their evaluation. An example of such a checklist is provided in Appendix H.
Focus groups involve selecting a group of visitors of a particular type and asking them as a group to discuss what they like and dislike about your community. Because group dynamics and the facilitator for the session can have a strong effect on the outcome of focus groups, it is good to do several of them, preferably using different facilitators. The difficulty of forming a focus group of visitors is finding an appropriate time and place to contact potential members. Many people that you approach, especially if they are on vacation, may not be interested, even if you are offering some incentive such as cash to participate.
XI. Conclusions
In this bulletin, we have outlined strategies for collecting information about tourism in your community and the economic contribution it makes. The most credible data source available to you is bed tax data because they are collected by an outside, disinterested source. It is possible to make fairly good estimates of lodging expenditures directly from these data. By making some assumptions about the percentage of total visitor expenditures on lodging, it is possible to come up with a rough estimate of total visitor expenditures (see Example 1). By keeping an inventory of hotels and their total number of rooms, you can track supply of rooms and room-nights in your community. If hotels and motels in your community are willing to share occupancy data, you can estimate demand for room-nights in the community. By combining this information with lodging expenditures, you can track average cost per room-night (see Example 3). Estimating the total number of visitors to the community is extremely difficult without conducting a survey of visitors. However, counting visitors to visitor centers, attractions and events can give you some indicators of visitor levels over time and allow you to assess how well individual attractions and events are doing in your community.
Tourism activity cuts across a number of sectors in the economy, so it is nearly impossible to track total tourism with secondary data. However, this information can be used to see how specific sectors like hotel and lodging, and eating and drinking places are doing over time in the community. Most of these data are available at the county level, but not for smaller communities, and are available several years after they are collected. National, regional and state studies, as well as studies from other communities, can give you some indication of the trends in tourism that may help shape your decisions concerning product development and marketing.
It is important to follow and respond to trends over several years, rather than one year's events. Example 8 presented one way to do this by estimating annual growth rates from bed tax data. You can also compare how your community is doing relative to other communities, the state, and the nation. Reviewing the trends and questions presented in Section VI in conjunction with the data you have collected can help you make tourism related decisions. In addition, consumer feedback from community swaps, focus groups, and postcard surveys can help you assess the quality of customer service in your community.
It is very difficult to estimate the economic effect that tourism and travel are having on a given community, but that does not mean that you should not use all possible information at your disposal to make these estimates. To be credible, it is important to explain how you made these estimates. The strategies presented in this bulletin should help you make a start on estimating tourism activity in your community.
