More than a quarter of people in West Lindsey were single as the number of marriage and civil partnerships dropped 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 West Lindsey when the census took place last year was 22,778, up from 18435 in 2011.
Of those aged 16 and older in West Lindsey, 28.8% were single – an increase on 25% 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 50.7% of people in West Lindsey were married or in a civil partnership last year – down from 55.1% 10 years prior.
Data from the census shows 39,797 people were in opposite sex marriages last year, down from 40,509 in 2011.
An additional 181 were in same sex marriages in West Lindsey last year – they were illegal in 2011.
The figures also show 108 people were in same sex civil partnerships last year and 29 were in opposite sex civil partnerships. There were 110 people in civil partnerships 10 years prior, which were only allowed for same sex couples at the time.
There were 8,357 divorced people and 20 people with a dissolved civil partnership in West Lindsey last year, making up 10.6% 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.
