Which Prefecture Has The Highest Proportion Of Women In Japan?

Answer

As of October 1, 2020, the total population of Japan, including foreigners, is 126,146,099, of which 61,349,581 are men and 64,796,518 are women, so there are 3,446,937 more women than men.

The composition ratios for men and women are 48.6% and 51.4%, respectively.

The prefecture with the highest percentage of women is Nagasaki-ken, where 53% are women (Table 1, Figure 1).

The prefectures with the lowest percentage of women are Aichi-ken, Tochigi-ken, and Ibaraki-ken at 50.1%.

Therefore, there are no prefectures where there are fewer women than men (Table 2, Figure 2).

Regional bias can be seen in prefectures where the proportion of women is lower than in other regions.

Table 3 and Figure 3 show the gender composition of all 47 prefectures.

The men and women columns in all tables indicate the respective populations.
