Labor productivity, often referred to simply as productivity
output per worker.

is the improvement in labor created by the education and knowledge of members of the workforce.
Real GDP per Capita
the key statistic used to track economic growth. It is real GDP divide by population size.
Key source of growth
technology. technological advance and improvement in human capital go hand in hand
Why do economists focus on real GDP per capita as a measure of economic progress rather than on some other measure, such as nominal GDP per capita or real GDP?
because real gdp alone does not take the population size into account, which doesn't necessarily measure the living standard. nominal gdp does not take the changes of prices due to inflation into account.
