The province of Treviso extends itself over a territorial surface of 2,476.68 sq km, for a total of 95 municipalities. The censused population at 31st December 2000 was 793,559, of which 389,485 males and 404,074 females. This data, referred to the whole territory of the province, results in a population density of 320 inhab./sq km, against the national average of 191 inhab./sq km and the regional average of 245 inhab./sq km.
The natural demographic increase (obtained from the natural balance on the average population in the year 2000) equals 1.5 newborns per 1,000 inhabitants, whereas the net migration rate of growth equals 10.5 immigrants per 1,000 inhabitants and is seven times as much as the natural increase rate.
As far as territorial areas are concerned, the natural increase rate is negative in the area of Vittorio Veneto (- 3,2); similarly, very low increase rates are registered in Quartier del Piave (0,5). However, these data are compensated for by substantial migration rates (13,9 in the area of Vittorio Veneto and 11,0 in Quartier del Piave), which can partly be linked with the labour request in the industry sector, as well as in the Opitergino-Mottense area, with a migration increase of 11.4 immigrants per 1,000 inhabitants.
As far as the Asolo and Castelfranco areas are concerned, the natural increase rate here equals 0.41 percent and 0.38 percent respectively, thus reaching the highest levels in the Province. As far as the area of Treviso is concerned, net migration here equals 12.1 immigrants per 1,000 inhabitants; this is due to the fact that the chief town is always an attraction point, both for employment and for services.
As far as the single towns are concerned, it can be observed that the highest migration rates concern small towns around Treviso, as well as small towns around Asolo and Conegliano. This phenomenon can be associated with the housing and living choices made by young couples.
