GetRatesC(): reads cohort mortality rates from the HMD and cohort
conditional fertility rates from the HFD. They are used to build virtual
populations from cohort data.
BuildViP(): builds a virtual population in a single step.
PartnerSearch(): replaces Partnership(). Individuals search for
partner in the same generation.
Other functions are updated to make the simulation more
efficient.
Data
New: ratesC.rda : cohort rates of mortality and fertility. The
cohort is the USA 1964 birth cohort. Since not all cohort members are
deceased in 2021, the mortality data are augmented by period data for
2021 (see Tutorial).
Removed: dpopus.rda. These data are used in the validation of the
simulation. They are moved to Zenodo.
Replaced: dLH:
dLH is replaced by fertility histories based on 2021 rates.
The IDs of children and the ages of mother at time of birth are
omitted from dLH. They are retrieved from the data on children (next
generation).
New variable: udated: date of union formation (not used).
Attributes added to distinguish between period and cohort data.
Vignettes
The vignette “Validation of a virtual population” is not included in
the vignette folder, but the PDF version is included in the doc folder
because the comparison of virtual and real populations uses register and
survey data that cannot be distributed.
