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.
