Percentages are the most misleading math application you can use in a debate.
Not in the case of a dynamic denominator. The labor force participation rate is the labor force as a percent of the correspondent civilian noninstitutional population. Posting number of total employed in 2010 vs 1990, 1970, 1950, etc. would create appearance of inflated results.
Anyway, denominator for workforce participation is US noninstitutional population over the age of 16 or ~ 80% of the total US population.
1990 US pop was ~248M
2010 US pop was ~310M
