## Demographics

Per Japanese census data, the population of Nagi in 2020 is 5,578 people. Nagi has been conducting censuses since 1920.

### Child subsidies

As of August 2005, the fertility rate was 1.4 children per woman. Measures were implemented to encourage having more children, including providing free medical care to children aged 18 or under, helping students going to high schools outside the town with their commuting expenses, and providing day care for sick children, as well as providing cheap rental properties and paying birth gifts of up to ¥400,000.
The fertility rate briefly increased to 2.8 in 2014, but according to an article in The Economist, one estimate gave the fertility rate as 1.9 by 2018, which was still higher than the national average. However, other figures from 2019 indicated a fertility rate of 2.9 that year. As such, the town’s higher birth rate, coupled with the financial incentives on offer has led to Nagi being referred to as a ‘miracle town’.
