Calculation and original data
Annual observations are year-end totals. Change is (comparison population ÷ baseline population − 1) × 100; national share is regional population ÷ national population in the same year × 100. Missing comparisons and zero denominators are not calculated. Averages and percentages are displayed to one decimal place.
