Using integrated administrative records on income tax and monthly household expenditures from electronic invoices, we estimate that, on average, the birth of the first child increases total household’s expenditure by 20% in the six months that follow childbirth, as compared to the months before the beginning of the pregnancy. The change in total household expenditure can be attributed to an increase of 52% in expenditures in retail trade, 36% increase in health expenditures, 16% increase in electricity and gas and 9% in water. We also observe a significant increase in education expenditures, but contrary to the previous categories, education expenditures only increase in the sixth month after childbirth.
