mwmapdata provides official spatial boundary datasets for Malawi, for use with the mwmap package or any spatial analysis workflow requiring Malawi administrative boundaries.

All levels include area_sqkm, center_lat, and center_lon columns.

Boundary data are the official Common Operational Datasets (COD-AB) sourced from the National Statistics Office of Malawi, distributed via OCHA Humanitarian Data Exchange (HDX), version 02 (valid from 05 April 2023).

• mw_level_2 contains 32 districts, including the 4 city districts (Blantyre City, Lilongwe City, Mzuzu City, Zomba City) added in the 2023 boundary update. Earlier datasets had 28 districts.
• mw_level_3 contains 433 traditional authorities, up from ~250 in earlier boundary versions.
• The major_lakes object contains Lake Malawi / Lake Nyasa. The administrative boundary source files do not include Lake Malombe or Lake Chilwa polygons.
• The malawi_data object is retained for backwards compatibility only and mirrors mw_level_2. Use mw_level_2 instead.
