Some researchers have managed to provide supporting evidence for the basic economic principle that increasing demand in excess of supply increases price.
19.21: immigrants as a share of population
17.71: 10-year percentage increase in housing prices
Keep in mind that these numbers are lower than they should be due to being artificially suppressed by the statistical artifacts of two debt-based housing crashes, as the researchers show both US and Spain showing a reverse correlation thanks to the big real estate crashes in 2008 and whenever the Spanish one took place.
Anyhow, the point is that the reason there are housing crises everywhere from Australia to the United Kingdom is immigration. It’s just one more piece of evidence that mass migration is catastrophic for a national economy.
