SANTIAGO, Chile (AP) — Chile's president is apologizing for mistakes in the country's latest census.

Sebastian Pinera said Thursday that he asks forgiveness from all Chileans for errors in planning and carrying out the 2012 census. He also says he'll propose a bill to make the National Statistics Institute independent of government control.

After a three-month evaluation, experts concluded Wednesday that the census has "serious problems" and shouldn't be used to calculate official numbers. Their report said 9.3 percent of the population was not counted.

Pinera had boasted earlier this year that the census was the best in the country's history.
