Minecraft wiki entry for Legacy_village_mechanics, associated text: The village center is the geometric center point, or "average coordinates" of all the doors. The village radius is the distance from this center point to the furthest door, or 32 blocks, whichever is greater. This means that the radius is always at least 32, no matter what, but it can be bigger if there are any houses further than 32 blocks from the center. The center point coordinates are truncated, resulting in a tendency towards 0,0.
