14 Demography Housing
14.1 population limit
14.1.1 balance checks
enough immigration* and/or emigration* for correction?
There are 0 records.
If no records: new_ims and new_ems were enough
-> no need to use new_ims2/new_ems2 and new_ims3/new/ems3
balance: check = pop_bir_dea + new_ims3 - new_ems3 - pop_limit
if the balance works, the new population should be the population-limit
i.e. the result should be zero and is in the range of -7.2759576^{-12}, 7.2759576^{-12}.
14.1.2 absolute difference
difference: population limit minus population (based on migration trends)
negative value: not enough space (immigration decreased, emigration increased)
positive value: too much space (immigration increased, emigration decreased)
14.1.3 relative difference
14.2 migration correction
14.3 smoothing over age
