Infanticide in early modern Japan? Demography, culture, and population growth

Migration, instead of infanticide, caused the stagnant population growth in Japan during the eighteenth and the early nineteenth century. Japanese wives were left alone when their husbands migrated from their homes to get better economic returns from work. The frequency of conjugal unions was reduced significantly due to work related migration, which negatively influenced population growth. The multiple components of demography worked together to make growth stagnant. Simplistic explanations based on mortality or fertility fail to explain the phenomenon.
