GDP Per Capita Varies

economic growth brings wealth, which increases well-being of a society
- economic growth: measured as an increase of people’s real income
- ratio between peoples income and the prices of what they can buy is increasing
- goods and services become more affordable, people become less poor
wealthier nations have:
- higher infant survival rates, life expectancy, and nutrition
- more educational opportunities, leisure, and entertainment
- fewer conflicts like civil wars and riots
- more material goods

for nearly all of recorded human history, there was no long-run growth in real per capita GDP
GDP was approximately equal in all major regions of the world, in other words, poverty was both widespread and equally distributed
today, GDP per capita is 50x larger in the richest countries than in the poorest
poverty is the historical norm
for most of recorded human history, there was no long-run growth in real per capita GDP
poverty is also the current norm, so the real question is no “how do we explain poverty?”
- real question is how to explain sudden appearance of relative wealth

GDO Per Capita: sum of gross value added by all resident producers in the economy plus any product taxes (less subsidies) not included in the valuation of output, divided by mid-year population
