Population change in certain areas may reflect how the coronavirus (COVID-19) pandemic affected people's choice of usual residence on Census Day, for example, students and in some urban areas.

These changes might have been temporary for some and more long-lasting for others.

First results from Census 2021 are rounded to the nearest 100 so may not add exactly.

Changes over time have been calculated with rounded estimates for Census 2021 and unrounded estimates from the 2011 Census.
