Use Historical Program Data for Accurate Estimation

If your program has been running for some time, historical data is your best guide for estimating unduplicated participants. Review past reports and records to see how many unique individuals were served, then use that data as a basis for your estimate. This method is especially reliable for established programs.

Leverage Local Demographic Data for New Programs

For new programs, demographic data from your local community can help you estimate how many people you’re likely to serve. Look at census data or local surveys that reflect the population in your target area. Align your program’s goals with the demographic data to make an informed estimate.

Conduct Surveys or Poll Your Audience for Direct Feedback

Another reliable method is to survey or poll your target population. Directly asking potential participants whether they would take part in your program gives you concrete data to support your estimate. This is particularly useful for new programs without historical data to rely on.

By following these three strategies—using historical data, demographic research, and conducting surveys—you can confidently estimate the unduplicated number of people your program will serve.
