Administrative reform
Originally, towns with a small population gathered and took the merger promotion policy of Heisei and became a "city" by applying the special provisions for promotion to the city, so the administrative power and financial power were strengthened according to the size of the population. Is an issue.In particular, the reduction of staff with a large number of staff compared to the size of the population is a mere situation.Since it is too late to replenish retirement, we are leading the top in cities and towns in Ehime prefecture, and we are recommending early retirement by giving preferential treatment by adding retirement allowance (since 2005).[Source required]..Another issue is the consolidation and integration of the seven third-sector companies that have been used in the old town.

The industrial base is weak and the economic power is poor.[3].

Formerly, the Uwa district (as a distribution center for rural supplies)Unomachi), There was an accumulation in the Nomura area, but especially in the Nomura area, it is declining due to the development of transportation and the exhaustion of the rural economy.For the Uwa area, the oldPost townExcept for Nakamachi, where the historic townscape remains, the roadside service industry has developed and attracts shoppers from the neighborhood.The economy is centered on the primary industry, and the concentration of manufacturing industries is scarce.For details, see the page of each old town.

Seiyo city areaHigh economic growthSince the 1960s, which is the period of the period, the population has been declining due to population outflow (social decline).However, the former Uwa Town is located in Higashiuwa District, taking advantage of the location of a transportation hub.Commercial-Service industryThe population has been maintained at around 1970 since the 1s by increasing the base of the company.Therefore, the population ratio of the former Uwa Town in Seiyo is on the rise. In 7000, the population ratio of the former Uwa Town in the former 1960 towns was 5%, but in 28.7 it increased to 2015%. It is predicted that it will reach 42.6% in 2060, and it is expected that the population will continue to be concentrated in the former Uwa Town.

In 2013, the social decline of 125 people (920 people moving in and 1045 people moving out) caused a population outflow.Capital Area-KeihanshinThe population migration is almost balanced with that of the major cities of Nanyo such as Yawatahama and Ozu.Most of the social decline occurred with Matsuyama City, resulting in an excess of 132 people moving out.

Special Honor Award Winner

Celebrity of origin (place of birth)

Place name

The expression "former XX town" is used several times in the notation of each section, but this is just to clarify the name of the relevant old municipality in the place of origin.Before the merger, there were 4 towns of Higashiuwa-gun (Uwa, Nomura, Akahama, Shirokawa) and 1 town of Nishiuwa-gun (Sanbin). It became a "city", and even if the county notation is changed to the city notation, the town name up to that point remains the same for each town.[21].

People outside the town may misunderstand that "Uwa-cho is also called Unomachi" and "Uwa-cho = Unomachi", but the name of the central area in the town of Uwacho, Seiyo City is It's just "Unomachi", and this is due to the confusion due to the place name of XX town. Called "Uwacho, Seiyo City"House displayIs not present, so it is correct to write the address in Unomachi as "○○ address of ○ chome ○, Uwacho, Seiyo City".However, the elementary school in the same town is written as Uwamachi Elementary School and read as "Uwamachi Elementary School".

Area code

0894 in the whole area.However, in Mikame Town and other areasMessage Area (MA)Is different.

  • Uwa Town, Nomura Town, Shirokawa Town, Akehama Town → Uwa MA
