The senior population is growing faster than the general population.
Between 2008 and 2018, the population of Americans over 65 grew by 35%, while overall population growth was 7.5%. The government is spending more (adjusted for inflation) on Social Security and Medicare as the population ages. Social Security payments for Old-Age and Survivors Insurance increased 42% over the decade, reflecting a 26% increase in the number of recipients and a 13% increase in the average monthly benefit payment.
Meanwhile, total Medicare payments increased 33% as the number of Medicare enrollees grew by 32% and the average cost per beneficiary rose by 4%
