摘要:4-H, like all Extension programs, must answer the charge to demonstrate its long-term impact. This article introduces the idea of using IMPLAN, a software program that can be used to estimate economic impacts, to evaluate the impact of 4-H livestock projects. An example is provided based on data from a real county 4-H program. Using IMPLAN enables 4-H to describe the estimated economic impact from one of its largest project areas. Agents can and should use IMPLAN results to help communicate the value of 4-H to state legislators, county commissioners, and key stakeholders.
