As of the last census, most of the central census tracts in Halifax were in the mid-to-high single digits, with the exception of 2050008 (
this area), with 10,325 per sq km, and 2050004.02 (
here) with 11,340 per sq km.
These numbers reflect data collected in 2020 for the 2021 census, though, and I suspect the numbers in 2026 will be substantially higher all over, given the huge amount of development in the past half-decade, which has disproportionately happened in the urban core. Estimates for the period between 2021 and 2024 show most central tracts growing between 20 and 40 percent in those three years alone, and developments has been keeping pace for the oast two as well. I think this city and a lot of others are going to find a stark difference between the two census, in a lot of ways, density among them.
