THE city's population is the highest it has been for 20 years, new figures show.
Census results from the Office of National Statistics have revealed there are now 256,406 people living in Hull – up from 246,355 in 2001 and 254,117 in 1991.
Figures for the East Riding show there are now 334,179 people in the area, which is an increase of more than 42,000 in the past 20 years.
The main increase is the number of working age people between 20 and 64 in Hull, which is up by 17,436.
The Lord Mayor of Hull, Councillor Danny Brown said: "The increase in the past ten years of the working age population shows people value Hull as a place to live.
"The city has benefited from £400m investment in our schools, we have had an exceptional decade of engaging residents in sporting and cultural events and we now have a developing City Plan which will put Hull on the map as the UK's leading energy port-city and make it a top cultural destination."
Every decade, the changing population and shifting social patterns of East Yorkshire are analysed when a bumper questionnaire lands on doormats across the region.
The statistics show there are now fewer young people under 19 in Hull, with a decrease of 2,988 in the past ten years.
There are also fewer people aged 65 and over than in 2001, with a decrease of 1,637.
Householders were asked questions about the number of people living in each home, their employment status, education and nationality.
Councillor Jonathan Owen, portfolio holder for performance, transformation and strategic partnerships at East Riding Council, said: "This information really helps us tailor our activities and shape our services to suit the needs of our residents.
"It shows quite clearly the pressures we're under as an authority with a huge increase in our ageing population, which is more than twice the national increase for this age group.
"This data is available to everyone via the council's data observatory website.
"As more releases are made over the next few months, we will put the information on there so residents can get more information about their local area."
