Abstract: Abstract We theoretically demonstrate that a decline in an economy’s total fertility rate occurs with urbanization. If there are no regional differences in fertility rates, the decline in the economy’s total fertility rate should be explained by a decrease in the number of children per woman. However, if there are regional differences in fertility rates, urbanization can depress the economy’s total fertility rate even if the number of children per woman does not decline due to urbanization. We construct an overlapping generations model with two regions (u and r). Region u has a lower fertility rate, but its higher wage keeps attracting more workers who will be parents. Since the economy’s total fertility rate is the weighted sum of the low fertility rate in region u and the high fertility rate in region r, urbanization and a decline in the economy’s total fertility rate are observed simultaneously, even if urbanization does not change the regional fertility rates. An implication for population policies aimed at increasing the economy’s total fertility rate is provided. Such policies must not only focus on increasing the fertility rate in each region, but also consider migration to regions with lower (higher) fertility rates.
