More than two in five people in Bath and North East Somerset were single as the number of marriage and civil partnerships dropped across the country in the past decade, new census figures show.
The area follows trends across England and Wales, where the rate of single people has increased since the last census in 2011.
The number of people considered single – never having been in a civil partnership or marriage – in Bath and North East Somerset when the census took place last year was 66,741, up from 54597 in 2011.
Of those aged 16 and older in Bath and North East Somerset, 41.3% were single – an increase on 37.3% in 2011.
The picture was similar across England and Wales last year, where 37.9% of people 16 and older were single, up from 34.6% in 2011.
And 43.4% of people in Bath and North East Somerset were married or in a civil partnership last year – down from 45.9% 10 years prior.
Data from the census shows 69,386 people were in opposite sex marriages last year, up from 66,961 in 2011.
An additional 447 were in same sex marriages in Bath and North East Somerset last year – they were illegal in 2011.
The figures also show 224 people were in same sex civil partnerships last year and 109 were in opposite sex civil partnerships. There were 309 people in civil partnerships 10 years prior, which were only allowed for same sex couples at the time.
There were 12,885 divorced people and 26 people with a dissolved civil partnership in Bath and North East Somerset last year, making up 8% of people aged 16 and over.
John Wroth-Smith, Census deputy director, said: "When looking a bit deeper, we can see that the proportion of people in a marriage or civil partnership has declined, which follows the long-term trend of declining marriages."
"Conversely, the number of people who were never married or in a civil partnership has increased by almost 3 million," Mr Wroth-Smith added.
Nationally, 21.7 million people were married or in a civil partnership – making up 45% of those aged 16 and older. And 9.1% of the population were divorced or no longer in a civil partnership, up slightly from 9% a decade prior.
