What was done
The authors examined the historical demographic transition in the United States between 1800 and 1940, presenting an economic framework to address how technological progress in agriculture and manufacturing accounted for shifts in fertility and rural-to-urban population distribution.
What was found
Between 1800 and 1940, average births per woman fell from 7 children to 2 children, and the proportion of the population living in rural areas fell from 94 percent to 43 percent. The authors attribute these shifts to technological progress in agriculture and manufacturing. No empirical test statistics, regression estimates, or confidence intervals are reported in the abstract.
Why it matters
The paper proposes a macroeconomic and technological explanation for long-term historical fertility declines and urbanization patterns in the United States.
Limits
The abstract reports only aggregate descriptive historical figures without detailing empirical methodology, microdata sample sizes, identification strategy, or formal statistical testing.
