The leader of the Liberal Democrats in Wales, Kirsty Williams AM, says while she welcomes the drop in teenage pregnancies, the rate is "still too high".
Teenage pregnancy rates in Wales have dropped by almost a quarter in the past decade, new figures show.
The Office for National Statistics figures said in 2011, 34 girls out of every 1,000 fell pregnant under the age of 18, down from 45 per 1,000 in 2001.
Julia Chandler, national officer for the Royal College of Midwives in Wales, said greater awareness of teenage pregnancy among teenagers, along with more availability of morning-after contraception, had contributed to the decline.
Despite the fall, the conception rate for under 18s remained higher than in England.
In 2011, 34.2 girls out of every 1,000 fell pregnant in Wales compared with 30.7 in England.
Merthyr Tydfil had the highest rate out of Wales's 22 local authority areas, with 54.1 out of every 1,000 girls aged 15-17 becoming pregnant. That figure was the fourth highest in England and Wales.
Blaenau Gwent saw the biggest fall in Wales, dropping by 32%.
