Dataset

Routine vaccination coverage — district reporting, 2024

Synthetic monthly DHIS2-style aggregate reporting of routine immunisation doses across 38 health facilities, with deliberate reporting gaps.

Files are versioned by filename. A corrected release ships as.v2.csv rather than replacing the file in place, so an analysis pinned to v1 keeps reproducing.

Data quality

  • Fully simulated. Coverage rates here do not describe any real district.
  • Denominators are annual targets, so monthly coverage must be computed against one twelfth of the target, not the full figure.
  • Facilities that did not report appear as rows with report_submitted false and no doses, not as missing rows. Treating them as zero doses will understate coverage.

Known issues

  • Reporting completeness drops sharply in August and September, which is intentional and makes this dataset useful for teaching completeness adjustment.
  • Three facilities report penta3 exceeding penta1, a common real-world data quality flag.

Example analyses

Python

Coverage and dropout rate by facility

Computes penta1 to penta3 dropout and flags facilities where the rate is implausible.

R

Coverage and dropout rate by facility

The same dropout calculation and flagging logic written with tidyverse verbs.

Adjusting coverage for reporting completeness

Shows how reported coverage shifts once completeness is accounted for in the denominator.
