Before carrying out analyses on a data set, it is usually desirable to trim it down by removing people you do not want to include. This can be done through the
keep commands in combination with standard IF conditions.
In the example below, the sample is trimmed down to contain people between 16 and 66.
//Connect to datastore require no.ssb.fdb:23 as db create-dataset demography import db/BEFOLKNING_KJOENN as gender import db/BEFOLKNING_FOEDSELS_AAR_MND as birth_year_month generate age = 2021 - int(birth_year_month / 100) keep if age >= 16 & age < 67
