A declining population causes economic contraction
Multiple economic and demographic studies confirm that population aging and declining demographic growth exert downward pressure on economic productivity and GDP per capita.
The retrieved literature consistently supports the claim that a declining or aging population hampers economic growth and productivity through reduced labor force growth and lower output, with no papers refuting the core relationship.
