There are "alarming variations" in the number of people with asthma admitted to hospital in an emergency, depending on where they live, says Asthma UK.
Figures for 2010-11 in England show that the admission rate for children in Liverpool was 19 times higher than in Tower Hamlets.
Adult hospital admission rates also varied widely across England.
