理容所と美容所 ── 1店あたり2人、そして高齢化した県ほど理容所が多い

Abstract

理容所・美容所の数を、衛生行政報告例(令和6年度末、厚生労働省)と経済センサス(令和3年、産業小分類782・783)で数え、都道府県ごとに比べた。 数は合わない。理容所は107,995対86,476(+24.9%)、美容所は277,752対161,280(+72.2%)。衛生行政報告例は許可を受けた施設、経済センサスは事業所である。 1店あたりの従業者は2人前後。理容所は1.80人/施設、美容所は2.12人/施設。ほとんどが1人か2人でやっている店である。 高齢化が進んだ県ほど、美容所より理容所が多い。美容所÷理容所の比は東京都の3.90から秋田県の1.39まで開き、高齢化率との相関はr = −0.668。一方で人口あたりの施設数はどちらも高齢化とともに増える(理容所 r = +0.792、美容所 r = +0.723)。高齢化が進んだ県は人口も少なく人口あたりの事業所が多くなるが、その中でも理容所のほうが多く残っている。北海道は比が1.97で47都道府県中39位。 この論文の位置づけ:新しい理論を主張するものではない。衛生行政報告例は許可を受けた施設の数で、廃業の届出が出るまで許可が残りうる。差が休業中の施設を含むかどうかで説明できる可能性はあるが、本稿では確かめていない。衛生行政報告例には市区町村別が無いため、単位は都道府県である。どちらの統計が正しいかを本稿は判定しない。 作成にあたって:本稿の着想と内容は、著者自身の考察に基づくものです。文章の構成整理や英訳、集計に用いたスクリプトの作成には AI(大規模言語モデル)の助力を得ました。最終的な内容の解釈や誤りがあれば、それらはすべて著者の責に帰します。お気づきの点があれば、ご教示いただければ幸いです。 ----- I counted barbershops and beauty salons in the Report on Public Health Administration (end of FY2024, MHLW) and the Economic Census (2021, subcategories 782 and 783), and compared them by prefecture. The counts disagree. Barbershops: 107,995 against 86,476 (+24.9%). Beauty salons: 277,752 against 161,280 (+72.2%). The former counts licensed premises, the latter establishments. Each shop has about two workers: 1.80 per premises for barbershops and 2.12 for beauty salons. Almost all are run by one or two people. The more aged the prefecture, the more barbershops relative to beauty salons. The ratio of beauty salons to barbershops runs from 3.90 in Tokyo to 1.39 in Akita, correlating with the share aged 65 and over at r = −0.668. Per head of population, however, both increase with ageing (barbershops r = +0.792, beauty salons r = +0.723): aged prefectures have small populations and therefore more establishments per resident, and within that barbershops persist more. Hokkaido's ratio is 1.97, 39th of 47. Scope of this paper: no new theory is claimed. The Report on Public Health Administration counts licensed premises, and a licence may remain until closure is notified; whether the gap reflects dormant premises is not tested here. The Report has no municipal breakdown, so the unit is the prefecture. This paper does not judge which statistic is correct. Acknowledgement: The ideas and content of this paper stem from the author's own considerations. Assistance from an AI (a large language model) was used for structuring, English translation, and writing the scripts used for the tabulation. Any remaining errors or misinterpretations are solely the author's. Feedback and corrections are sincerely appreciated.
