Brazilian Infant Mortality and Live Birth Records Linked for 2011-2012

Brazilian capitals in 2012 provide data on 9,001 infant deaths and 1,424,691 live births from 2011-2012. The dataset results from a linkage study by Lívia Teixeira de Souza Maia, which paired records from the Mortality Information System (SIM) and Live Birth Information System (SINASC) to improve data completeness. It focuses on 11 common variables between the two systems, with linkage recovering 91.4% of previously incomplete fields.

Use Cases

• Assessing data completeness improvements based on the 11 common variables between SIM and SINASC.
• Analyzing regional disparities in data quality based on the described variation in linkage success across Brazilian capitals.
• Evaluating record linkage techniques (deterministic and probabilistic) for public health databases.
• Studying infant mortality factors using the linked birth and death records.

Strengths

• Covers 9,001 infant deaths and 1,424,691 live births, providing substantial scale for analysis.
• Linkage successfully recovered 91.4% of 11,278 previously incomplete data fields.
• Geographic coverage includes all Brazilian capitals, allowing for regional comparisons.

Limitations

• Row count for the final linked dataset is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
