**Full name:** Predicted Population Development 2022 to 2030 in Percent (Base ROP 2045) **Algorithm:** Forecast model **Note:** As the method of the BBSR population forecast, the period model commonly used in official statistics with the annual cohort-wise update of the population stock is utilized. Additionally, natural and spatial movements are included in the update. This approach is also referred to as the cohort-component method. Births, deaths, and migrations are derived from rates in the population, trend-based where possible, otherwise from current average values. A unique and special component of the BBSR model concerns internal migration, where the departures from all sub-areas are simultaneously distributed to the target areas. The empirical basis for this is the actual migration interconnection between the districts of the recent past. Detailed information on the methodology can be found in issue 13/2024 of BBSR-Analysen KOMPAKT as well as in issue 4/2024 of BBSR-Analysen KOMPAKT.

The dataset Population Projections provides the expected development of the population based on ROP 2045 and indicates the changes compared to the base year 2022 in percent. Percentage changes are shown for the periods up to 2030, up to 2035, up to 2040, and up to 2045. The data is available for the spatial levels of district and postal code, enabling detailed regional analyses. The dataset supports the assessment of growth and decline trends, comparison between regions, and forward planning in areas such as infrastructure, housing, and public services. The uniform reference basis and consistent methodology allow developments to be tracked across multiple forecast horizons and reliably integrated into strategic decisions.
