> The math don't math. It's a drop in the bucket. Since this is HN, I was expecting a little more rigor in proving the math not mathing: how many people can be housed in 15 000[1] + 10 000 houses? How small is the drop and how big is the bucket? From sibling comment, average density is 2.51 people per home * 25k houses which works out to 62 750 housed people out of the 100 000 population growth. If my math is correct…
The 15k houses were built over 10 years, but the 100k growth is over 4 years. So 4/10ths of 15k ~= 9k/47k housed. I think it's fair to say I'm being dramatic by saying it's a drop in the bucket. The action frees up more housing than Barcelona built over the same time period. This is good. However, it's still not a long-term solution. This is a one-time action that when taken, and combined with the housing being built…
The larger context is Spain’s population is flat with declines in the last 24 months and trend likely to continue in the coming decades. Barcelona’s population peaked in 1979 and only recently recovered to the level seen in 1990. So they likely don’t actually need to add significant housing long term. Freeing up AirBnB apartments in the short term looks like a reasonable solution until population decline kicks in and removes the need for extra housing.
