The top baby names for 2019 have been revealed with the most popular boys’ and girls’ name remaining unchanged once again.

It’s the sixth year in a row Oliver has topped the list while Charlotte has been the most popular for the last three years.

Noah, William, Olivia and Mia round out the top three in each gender.

The top names have remained consistent in recent years but they far less popular than in decades past.

Just 449 baby girls were named Charlotte and 568 boys were named Oliver in 2019, compared with the 1647 girls and 1486 boys receiving the top names of Jessica and Matthew in 1990.

BDM data also revealed the top middle names with James, John and William most popular for boys and Rose and Grace for girls.

Parents have 60 days to register their newborn’s name, establishing the child’s legal identity.
