One way of assessing housing demand or shortages is to consider population growth compared with the number of dwellings available.
Here’s is how our calculation works:
- In 2013, the estimated population in Hamilton City was 150,200 and the number of dwellings (occupied and unoccupied) was approximately 53,700.
- In 2016, the estimated population was 161,200 and the number of dwellings (2013 figure plus estimated additional housing stock) was approximately 56,300.
- Based on 2013 occupancy rates, this leaves Hamilton with a shortfall of approximately 1300 dwellings.
 The number of consents for new dwellings in Hamilton between June 2013 and March 2016 was 2981 dwellings. A number of these are not built and some existing dwellings are demolished over time so the consented dwelling count needs to be reduced by a factor to get an estimate of the actual number of additional dwellings in the housing stock. To get this reduction factor the number of consents issued between the March 2006 census and the March 2013 census was compared with the census count of occupied and unoccupied dwellings to establish what proportion of new consents resulted in additions to the housing stock.
