La popolazione elvetica è ulteriormente aumentata nel 2015: l'incremento è stato dell'1,1%, ossia 87'500 persone e, a fine dicembre, i residenti erano 8'325'200. Ed è grazie agli stranieri, quasi un quarto degli abitanti (+49'100), che il saldo demografico continua ad essere nettamente positivo; anche gli svizzeri (+38'500) hanno però dato il loro contributo.
Sul piano cantonale, sempre stando ai dati pubblicati giovedì dall'Ufficio federale di statistica, il saldo naturale favorisce l'aumento della popolazione in quasi tutti i cantoni, in particolare a Zugo, Friburgo e Ginevra. Solo Grigioni, Soletta, Basilea-Campagna, Uri, Sciaffusa, Basilea-Città e il Ticino registrano più decessi che nascite.
Una donna su cinque e un uomo su sei hanno più di 64 anni. La quota di donne con oltre 65 anni è già superiore a quella delle donne giovani (il 19,9% contro il 19,4%). Prosegue la progressione dei centenari: 1'600 (+0,6%, con una proporzione di 100 donne contro 23 uomini).
