You're not as bad as Patrick Condon! It doesn't quite work that way. Most of the population in the census are classified as living in private households, and some live in other arrangements (collective housing, homeless, incarcerated, in hospital etc).
In 1971 there were 426,760 people identified in the census in the City of Vancouver, with 408,705 of them living in 153,335 private households. That gives you an average household size in 1971 of 2.665 (which they round to 2.7). The rest of the population (18,055 people) were in some other living arrangement, but not a house, or apartment.
In 2021 the total population was 662,248 and 650,380 lived in 305,335 private households. (The other 11,868 were in another living arrangement). That gives you an average household size in 2021 of 2.13, (hence the quoted 2.1).
