OTTAWA - Statistics Canada says employment among landed immigrants in the core working-age group of 25 to 54 increased 4.3 per cent in 2011 compared with the previous year.

The agency says employment among Canadian-born workers in this age group was virtually unchanged during the period.

It says that the employment rate for landed immigrants in this key age block was 75.6 per cent in 2011, well below the 82.9 per cent rate for their Canadian-born counterparts.

The agency says most of the employment growth occurred among established immigrants who had been in the country for more than 10 years.

And the 2011 employment rate for core-aged landed immigrants was still 1.8 percentage points lower than in 2008, the start of the economic downturn.

That's because their growth in employment did not keep pace with the growth in their population.
