These data do not track the same people
Moves are events
The count is based on registered moves and is not a count of unique people. A person moving more than once during the period may be counted repeatedly.
Denominator for the mobility rate
The rate divides net moves by the registered population of the same age group at the end of the observation window, per 1,000 people. Read it beside the count.
Loans are an average among borrowers
The balance at the reference date is divided by the number of borrowers. Non-borrowers are excluded, and borrower entry, exit, and composition can also affect changes.
Compare side by side, not as a causal chain
The two datasets are not linked at the person level. They compare phenomena observed in the same region and period and do not establish a causal relationship from moving to borrowing.
Matching spatial resolution
Routes use provinces; the comparison uses ECOS's six regions. Moves between provinces inside the same ECOS region cancel in that region's net balance.
