The number of teenage pregnancies in East Staffordshire has fallen since 2011.
The figures, collected by the Office for National Statistics, show that in 1999 around one in 20 females conceived their first child under the age of 18, with about a quarter of these being conceived under 16.
In 2011, the number had decreased to approximately one in 35.
A spokesman for the Office for National Statistics said: "Research shows that young women from socially disadvantaged backgrounds and those with poor educational outcomes are more likely to have a teenage pregnancy.
"Historically, areas with high teenage conception rates have also had relatively high deprivation measures, such as unemployment rates, but this doesn't mean that one factor causes the other."
