Comparing the CMHC housing starts data with data from the 2001 Census for the GGH leads to the following observations:
- The share of single detached houses is similar in the two data sets, at 53.7 percent in the CMHC data and 54.1 percent in the census data (which includes attached houses and mobile homes).
- The share for semi-detached houses is slightly higher in the CMHC data (9.2 percent) than the census data (7.2 percent).
- For row houses, the share has increased considerably in the CMHC data (15.1 percent) compared to the census data (7.4 percent).
- For apartments, the CMHC starts data shows a 22.1 percent share, which is considerably lower than the 31.3 percent in the census data (including the three categories of apartments).
