Data collection

Extract from the Danish Immigration Service's register.

Data validation

The number of asylum applications and residence permits are not checked for errors.

Immigrations without residence permits are imputed.

Data compilation

Immigrations of people with a citizenship outside Denmark and the Nordic countries are linked with their respective residence permit. For those immigrations which can't be linked with a residence permit due to missing CPR-number in the register on foreigners the residence permit is imputed.

The imputation consists of a method known as donor imputation. This means that all the immigrated within one calendar year are grouped by sex, age, marital status and citizenship. The distribution of residence permits which e.g. married men age 18-24 with a Pakistani citizenship will hereafter be applied to the same group which has not been linked to a residence permit.

Adjustment

There is no correction of data except what is mentioned under "Data validation" and "Data compilation".
