The number of dwellings in Narrabeen is forecast to grow from 4,180 in 2021 to 4,780 in 2041, with the average household size falling from 1.98 to 1.96 by 2041.

This summary shows the results of the forecasts for population, households and dwellings in the Northern Beaches Council. The period 2021 to 2031, as the short to medium term, is likely to be the most accurate and useful forecast information for immediate planning purposes.

It is important to look at the relationship between population and average household size. If the average household size is falling, then there will need to be growth in the number of households (and dwellings for them to live in) to maintain or grow the population.
