British parents kept Oliver and Olivia at the top of the baby-name charts for a second year in 2010, with Jack and Sophie in second place.

Data published Thursday by the Office for National Statistics in London covering the 723,165 live births in England and Wales in 2010 showed that the four most popular boys’ names — Oliver, Jack, Harry and Alfie — were all unchanged from 2009. Charlie moved up two places to fifth.

For girls, Sophie rose three places to second, Emily was up one to third, Lily climbed four to fourth and Amelia was up four places to fifth.

Ruby and Chloe fell out of the top five.

There was more variety in girls’ names, with 34,700 registered, compared with 27,700 registered for boys.
