Level of per capita GDP depends upon which of the following? 1. Proportion of population in the working age 2. Work participation rate 3. Per worker productivity

Per capita GDP can be decomposed as: GDP/Population = (GDP/Workers) × (Workers/Working-age population) × (Working-age population/Total population). This is equivalent to multiplying per-worker productivity, the work participation rate, and the share of the working-age population in total population. Hence per capita GDP depends on all three factors — demographic structure (proportion of working-age population), labour market engagement (work participation rate), and labour productivity (output per worker).
