Social impacts of vacant houses
The vacant houses which are not in use nor on sale are losing opportunities.
And even if there are people who want to open a shop there, the vacant houses prevent it.
A new shop could revitalize the community so the losing opportunities is not desirable at all.
The more people leave the area because of external economy and losing opportunities, the more vacant houses we have.
It is said that if the vacant house rate becomes 30%, the finance of the local government collapse.
Actually in Yubari City in Hokkaido Japan, whose finance collapsed in 2007, the rate was 33.01% and Detroit City in the US,
which had the biggest finance collapse in history, the rate was 29.3%.
If a town has 500 houses where people live, the local government will prepare the infrastructure for all these houses.
For example, they have to set up police boxes, fire departments, traffic signals, streetlamps and roads.
However, there is no problem with it because the town receives enough tax revenues from 500 households.
We can say the same thing for a town which has 350 houses where people live.
The density of a town means how many shops or houses there are in a certain area.
When the population of a town increases and the town grows up, the town expands without any order.
On the other hand, when the population of a town decreases and the town shrinks,
the number of the vacant houses increases in many places in the town.
The burden of the town increases, because the density of the town decreases.
The number of customers who visit the restaurant and convenient store decreases and many shops leave the area.
In conclusion, the town shrinks.
