Il Ticino ha superato quota 350'000 abitanti a fine 2014. Erano 350'363 a fine anno, 3'824 (1,1%) in più rispetto al 31 dicembre 2013. L'incremento è leggermente inferiore sia a quello degli anni precedenti che alla media nazionale. La popolazione elvetica è cresciuta dell'1,2% pari a 98'035 persone portando il totale a 8'237'666.
Evoluzione della popolazione
All'aumento della popolazione ticinese contribuiscono tutte le regioni, comprese le valli, anche se è nel Luganese che la crescita è più evidente. I dati dell'Ufficio federale di statistica evidenziano pure l'aumento delle quote di stranieri (ora il 27,6%) e di ultra 65enni (21,6%).
Lieve incremento nei Grigioni
Gli abitanti del canton Grigioni erano invece 195'866 il 31 dicembre, 927 in più rispetto a un anno prima, e l'aumento è da ricondurre essenzialmente alla popolazione straniera (+2,5% a 35'389 unità), che ora rappresenta il 18,1% del totale. Il tasso di crescita è dello 0,5%, in linea con il recente passato.
Le variazioni nelle regioni dei Grigioni
Le cifre evidenziano anche uno sviluppo non omogeneo fra le varie regioni retiche: Surselva, Davos ed Engadina Bassa hanno addirittura perso abitanti, così come la Bregaglia.
I calanchini erano 791 a fine 2014, l'1,9% in più in un anno
Restando al Grigioni italiano, +0,3% per Poschiavo e Mesolcina e sensibile incremento per la Calanca, +1,9%.
