These registers are normally used to study social distributions with respect to abuse within a larger population. In countries where every person has a unique personal identity number, it is relatively easy to link different registers, allowing for powerful analyses of complex research questions.

•If important changes have been made in how data has been registered and when

•If specific subgroups of people are not included or omitted from the registers
