School Entry Age Effects on Family Formation in Vietnam

Replication data supports a study on the causal impact of school-entry age on long-run family formation outcomes for 14 million individuals in Vietnam. The analysis uses quasi-experimental evidence from Vietnam Population and Housing Censuses. The replication code and data links were provided by author Ishaan Busireddy in April 2026.

Use Cases

• Estimate causal effects of school-entry age on marriage timing using census-derived age and marital status variables.
• Analyze the relationship between educational timing and fertility outcomes using census data on children ever born.
• Replicate quasi-experimental regression discontinuity designs with individual-level census identifiers and birth dates.
• Study geographic heterogeneity in policy effects using regional codes from the Vietnam censuses.

Strengths

• Analysis covers approximately 14 million individuals, providing substantial statistical power.
• Leverages three decennial census waves (1989, 1999, 2009) for longitudinal perspective.
• Data originates from official national censuses conducted by Vietnam's General Statistics Office.

Limitations

• Primary census microdata requires separate registration and data use agreements with UK Data Service and IPUMS.
• The dataset provided is replication code; the underlying individual-level data is not directly included.
• Census data may have reporting errors or omissions common in large-scale administrative collections.
