Where Madagascar's land ends up, by people and by money
Every block on the map is 0.1% of Madagascar. By land, Analamanga holds 2.8%. By people, it holds 20%. Atsimo-Andrefana goes the other way, from 12% of the land to 6.5% of the people.
GDP for Madagascar is modelled from its national total, so the GDP map mostly repeats the population map.

How the map is made
Regions are drawn on an equal-area grid of about 1,000 blocks. For land, each region keeps the blocks its territory covers. For people and GDP, the country is reshaped so every region gets a whole number of blocks in proportion to its share (Hamilton's largest-remainder method), keeping neighbours next to each other. Then every block is matched to one block on the next map, so you watch the same thousand blocks rearrange.
