How much of the GDP has social security comprised every year from its inception to today?

Question

I want to know how much of the Gross Domestic Product is made up of social security every year from its inception until today.

For example, did social security make up 10% of the GDP in 1936, 14% of the GDP in 1958 and 33% of the GDP today?

Answer 1

You can compute it yourself:

Social Security and unemployment insurance contributions are given on lines 7 and 8 in the NIPA table 2.1:

Nominal GDP is found on line 1 of the NIPA table 1.1.5:
