Last year's General Household Survey shows the average monthly household income from work dipped to $1,180, or by nearly 20 per cent, for the 11th to 20th percentile of wage earners, and to $2,190, or by about 5 per cent, for those in the 21st to 30th percentile.

Ironically, it was the top 10 per cent of wage earners who enjoyed the largest increase in monthly household income. The average of $16,480 was 14.8 per cent higher than the $14,360 earned by this group in 2000.
