Not at my fingertips but my guess is that it'd be the same or slightly higher than the GDP share. Over the last few years, US consumption has inched above 70% of GDP (after being in the mid-60s in the 1990s and the low 60s in the early post-WW2 decades). That's higher than most other countries (which have higher investment, government, and net export shares).
