propop 1.2.1

• get_population: Using clearer, more intuitive name for argument to specify start year; less typing for users;
• revised function documentation
• More detailed feedback after running propop::propop(), stating which arguments were used)

propop 1.2.0

• Added function calculate_shares to distribute FSO estimates expressed as "number of people" among sub-cantonal entitities (e.g., immigration to municipalities).

propop 1.1.0

• Added unit test that fails if projection outcomes differ from FSO projections
• Increased flexibility of prepare_evaluation() by offering possibility to indicate which column contains the population (rather than assuming it's called n).

propop 1.0.0

Projection using separate parameters for migration between cantons

• propop::propop() now uses separate input parameters for emigration to / immigration from other cantons. Previously propop::propop() used the net difference between emigration to / immigration from other cantons.
• With this change, the new version now directly corresponds to the projection equations provided by the FSO.
• The change has also facilated the inclusion of all components of the cohort component method in the output. This makes it easy to track the transition from one year to the next.

New variable names

• This change required a comprehensive renaming of several variables, which makes the new version incompatible with previous code.
• If you want to continue using old code, we suggest using version 0.2.0. Note that the components of the projection equation are not included in the output in version 0.2.0.

propop 0.2.0

Projection without distinction of nationalities

• If desired, projections can be run for only one nationality (no longer required to provide two nationalities).
• propop::propop() returns a plain text feedback in the console summarizing the settings used to run the projection.

propop 0.1.0

Development history and earlier versions

The propop package is a successor of staagBevProj (not publicly available), which was last updated in December 2022. staagBevProj was developed by Tina Cornioley, Jan Wunder, and Niklas Haffert. As head of Official Statistics Aargau, Andrea Plüss supported the devlopment as well as the publication of staagBevProj and propop.

propop was developed by Norah Efosa and Adrian Gadient (Statistik Aargau). The main innovations are:

• Clearer separation between code that prepares data and code that runs the projection
• Centrally united FSO parameters and corrections / adjustments; these are now gathered in a single data frame that is passed to the projection function
• Only one function to run projections (rather than projectPop and projectAll)
• Convenience functions to directly download data and parameters from STAT-TAB
• Incorporation of assertions and unit tests
• Function to evaluate projection results
• Clearer documentation
