A GIS + data analytics pipeline that measures physical access to healthcare facilities across nine African countries — five in East Africa (Kenya, Uganda, Tanzania, Ethiopia, Rwanda) and four of Africa's more industrialised economies (South Africa, Egypt, Morocco, Tunisia) — and benchmarks them against each other and against published research.
# Healthcare Access Africa — GIS Benchmarking Pipeline
This is a GIS + data analytics pipeline I built to measure physical access
to healthcare facilities across nine African countries — five in East Africa
(Kenya, Uganda, Tanzania, Ethiopia, Rwanda) and four of Africa's more
industrialised economies (South Africa, Egypt, Morocco, Tunisia) — and
benchmark them against each other and against published research.
I set it up to run **end-to-end out of the box** on synthetic sample data,
so anyone cloning it can see the full pipeline work immediately. It's also
built so I can drop in **real facility data** and get a real, sellable
analysis — see Using real data
below.
## What this actually does
1. Loads a country's boundary polygon (real data — see Data sources).
2. Loads health facility point locations (**synthetic/sample by default**).
3. Buffers each facility by a chosen radius (default 5 km) in an equal-area
projection, so distances are measured in real metres, not degrees.
4. Computes what % of the country's **land area** falls within that buffer.
5. Generates a map per country and a comparison bar chart across all nine.
6. Joins the result against a table of **real, cited, published** accessibility
figures (`data/reference/published_access_benchmarks.csv`) pulled from
peer-reviewed geospatial studies, so I can see where my own analysis
lines up with, or fills a gap in, the existing literature.
### Area coverage vs. population coverage — read this before presenting results
The pipeline computes **% of land area** within N km of a facility. That's a
legitimate, standard GIS screening metric, but it is **not** the same as
"% of population" within N km — the number funders and governments actually
care about, because people aren't spread evenly across land area. Sparse
land (northern Kenya, the Sahara in Egypt/Morocco) will always look like a
bigger "gap" on an area basis than a population basis.
To get a population-weighted figure — the metric used in the publ …
