A person moving within the municipality, for example, from one village to the next, codes 1. A person moving within the province, say from a rural municipality to the province capital codes 2. A person moving within the same community yet leaving their province codes 3. A person moving from one community to another, say from [Andalusia](https://en.wikipedia.org/wiki/Andalusia) to [Galicia](https://en.wikipedia.org/wiki/Galicia_(Spain)), codes 4. If the person moved from outside the country (regardless of their nationality) codes 5.
