Temporary Assistance for Needy Families (TANF) data is collected on the last day of every month and represents a snapshot in time. For instance, the data that displays for January reflects all of those who were enrolled in a TANF program on January 31. It is not appropriate to aggregate all months together to form a yearly total for participation. It is likely that many enrollees may be enrolled for several months of the year, and thus would be counted in the snapshots for each of those months.
