Brazil administered 388 million COVID-19 vaccine doses. This study examines the quality of age reporting in the national vaccination database—comparing 387 million records with census data, demographic projections, and high-quality data from Sweden.

This project provides the R code and reference data for the first study comparing population estimates for the oldest old using administrative vaccination data and census data in Brazil.

Data and reproducibility

The R code and reference data files are available for download. The IBGE, UN, IPUMS, HMD, and CONASS reference files are in data-raw.

The main microdata file — 387,750,333 vaccination records, approximately 190 GB — is archived at DOI and should be downloaded into data-raw.
