Sample parameters to run population projection

Data frame containing the rates and number of people from the Federal Statistical Office (FSO) required to project the development of four demographic groups for a selected canton (Aargau). The parameters are from the model published in 2025. The sample data include three scenarios for the years 2024-2055.

Usage

fso_parameters

Format

The example data include the required parameters for each demographic group (nationality (2) X sex (2) X age classes (101)) for the years 2024-2055.

Demographic groups

The returned data frame includes parameters for each unique combination of the following demographic variables:

• nat: ch = Swiss; int = foreign / international.

• sex: f = female, m = male.

• age: 101 one-year age classes, ranging from 0 to 100 (including those older than 100).

Parameters

The following parameters are included in the returned data frame:

• start_n: numeric, number of people in the corresponding demographic group on 1st of January.

• year: numeric, year of projection.

• scen: character, projection scenario.

• spatial_unit: character, indicating the user requested spatial unit(s).

• birthrate: numeric, total number of live human births per 1,000 inhabitants. (formerly birth_rate).

• int_mothers: numeric, proportion of children with Swiss nationality born to non-Swiss mothers (formerly births_int_ch).

• mor: numeric, prospective mortality (probability of death).

• emi_int: numeric, rate of people emigrating to other countries (formerly emi).

• emi_nat: numeric, rate of people emigrating to other cantons (new parameter).

• acq: numeric, rate of acquisition of Swiss citizenship.

• imm_int_n: numeric, number of people immigrating from abroad (formelry imm_int).

• imm_nat_n: numeric, number of people immigrating from other cantons (new parameter).

• emi_nat_n: numeric, number of people emigrating to other cantons (parameter previously used to compute mig_nat_n).

• mig_nat_n: numeric, national / inter-cantonal net migration (number of immigrants minus number of emigrants). (formerly mig_ch, will soon be obsolete and removed).

Projected population

n_projected is the number of people per demographic group and year on December 31 (as projected by the FSO in the 2025 model).

Details about calculated variables

births_int_ch is calculated by dividing the number of live newborns with Swiss citizenship born to non-Swiss mothers by the number of all live newborns born to non-Swiss mothers.

mig_ch is calculated as the difference between the immigration from other cantons and the emigration to other cantons.
