  • Transfers, Interest Payments, and Subsidies are not included. If we include those, the graph looks like the following:

The Breakdown of Social Security payments into its three components comes from SSA ASS Table 5j. The total values at the top include payments to people living in Territories and abroad. In contrast, the values from BEA Table 3.12 separates transfers to non-US residents (Puerto Rico, mainly) into a separate line item.
