Professor Hiroshi Yoshida of the Graduate School of Economics, Tohoku University and others recalculated the total fertility rate (* 2015) by prefecture before 1 using the correct method. It turns out that recovery is stagnant in the Tohoku region.The four prefectures of Iwate, Miyagi, Yamagata, and Tochigi have fallen to record lows in 2005.
According to Tohoku University, the research group of Professor Yoshida and others pointed out that there is a problem with the method of creating the index value of the total fertility rate by prefecture announced by the Ministry of Health, Labor and Welfare, and the Ministry of Health, Labor and Welfare revised the index value after 2016. However, the index values before 2015 have not been revised.Therefore, Professor Yoshida et al. Recalculated the index values before 2015 by the correct method (commonly known as Tohoku University birth rate).
As a result, after recording the lowest total fertility rate so far in 2005 in all prefectures, Akita prefecture has entered a reversal phase except that it reached record lows in 2010 and Fukushima prefecture in 2011-2012. It became clear.
However, in 2019, the total fertility rate dropped sharply, mainly in the Tohoku region, with Iwate prefecture 1.35, Miyagi prefecture 1.23, Yamagata prefecture 1.40, and Tochigi prefecture 1.39 recording record lows.In particular, Miyagi Prefecture has the second lowest number among all prefectures in Japan after Tokyo.
When ranking the total fertility rate recovery status from 2005 to 2019, the top three were Miyazaki prefecture 0.25, Nagasaki prefecture 0.21, Tokushima prefecture 0.20 and southern countries, but the lowest Iwate prefecture recorded minus 0.06. Including Aomori prefecture, 5 prefectures in Tohoku and Tochigi prefecture are below the index value in 2005.
