2. ODA for health	ODA that targets general and basic health, as well as population policies/programs and reproductive health (as defined by the OECD purpose codes 120, 130, 16064) (8). In this study, we focus on bilateral ODA.
3. General government expenditures (GGE)	Total government expenditures across all sectors, including health (9).
4. Domestic general government health expenditure (GGHE-D)	Health expenditures that come from the domestic government (9).
5. UK ODA/Total ODA	UK ODA as a share of total ODA for a given country shows the degree of reliance on UK ODA out of all ODA.
6. ODA/GGE	ODA to GGE shows the degree of a government’s reliance on external aid.
7. UK ODA/GGE	UK ODA to GGE shows the degree of a government’s reliance on UK aid.
8. Health ODA /GGHE-D	Health ODA to GGHE-D shows the reliance of a government’s health system on external health ODA.
9. UK health ODA /GGHE-D	UK health ODA to GGHE-D shows the reliance of a government’s health system on UK health ODA.

The OECD CRS data was used to identify ODA data from external donors (10). We used 2019 disbursement data for our analysis, the latest available data (Indicator 1,2,5,6,7, 8, and 9). The GHED was used to identify domestic government expenditures overall and within the health sector. We used 2018 expenditures data for our analysis, the latest data available (Indicator 3,4,6,8 and 9) (11).
