Overview

Historical policy changes aimed to improve education and food availability, influencing child mortality and lifespan.

Key Points

  • The analysis looks at how changes in the institutional environment can affect human life-histories.
  • Evidence suggests that policy changes reduced child mortality but had less clear impacts on lifespan and family size.
  • Interrupted time series analysis and generalized additive models provided insights into the non-linear data over time.
  • Findings indicate improving living standards, yet the life-history implications of the changes remain complex.
