Saskatchewan's population has jumped by more than 22,000 in the past year — equivalent to adding another Estevan and another Weyburn.

It's the biggest growth in one year since 1921 and brings the total to 1,079,958 as of July 1, 2012, Statistics Canada reported on Thursday.

The extra 22,154 people represent an increase of 2.1 per cent, the second highest in Canada after Alberta (2.5 per cent).

The population was growing particularly fast in the last quarter, with 6,851 added.   Of those, 1,373 were people coming from other provinces, 4,035 were people from other countries and 1,443 were due to natural increase (births minus deaths.)

Saskatchewan's growth rate due to international immigration was noted as tops in Canada at 1.3 per cent.
