and deaths) and migrations. The population development is analysed retrospectively and prospectively (projections/scenarios).

These statistics must provide:

- Information on the changes (births, deaths, migrations) and development of the resident population as well as demographic balances.
- Information about the spatial distribution of the population in Switzerland. This information is available at the cantonal and communal levels, but also for small units below the commune level.

These are the main topics covered:

- Size and structure of the population (by age, sex, nationality, marital status, etc.)
- Population development
- Distribution of the population
- Scenarios of future population trends in Switzerland and the cantons
