#7 The average age for first love in the UK is 18 – the same as the average age for first heartbreak


The average age for a first boyfriend in the UK is 17, but people typically fall in love for the first time when they’re 18 by meeting their first serious boyfriend or girlfriend. Sadly, this is also the age when young people experience their first heartbreak. 18 is a tumultuous age!

#12 People over 30 form longer-lasting relationships

(Love to Know)

Once people turn 30, they begin forming more committed relationships; once the relationship crosses the one-year mark, the probability of a break-up decreases.

Relationship statistics for the UK reveal that 90.5% of the population aged 16-29 is single, meaning they have never been married or in a civil partnership.

#14 Divorce rates are higher in couples with a large age-gap

The divorce rate in couples close in age is 3%, with the percentage jumping to 6% for couples that have a 20-year age gap.
