Estimate Service Needs In Your Rural Community

There are two phases in the capture-recapture method. In the first phase, all members of the target population in a given area are counted. In the second phase, researchers return to areas frequented by members of the target population to count again. The population size can then be estimated by multiplying the number of individuals counted in the first phase by the number of individuals counted in the second phase. That number is then divided by the number of individuals who were counted in both phases to calculate a population estimate.
