Key facts for Dorset

Dorset has a lower birth rate than Bournemouth, Poole and England & Wales, but a higher death rate, meaning if it were not for in-migration into the area, the population would decline. It has a smaller than average under 5's population but a higher than average population of over 65's meaning there is increasing pressure on adult and care services. The projected growth in our population is expected to further increase pressure on services, as the over 65's population grows by 50% over the next 25 years.
