What does this graph show?

The level of underage pregnancies has fallen right across London in the last decade. Almost all boroughs (30 out of 32) saw a fall, and the fall in London has been greater than the fall nationwide. The rate of underage pregnancies in London was 4.8 per 1,000 in 2011 to 2013, compared to 5.5 in England on average. At decade earlier the average for London was higher than for England overall (9.9 and 8.0 per 1,000 respectively).

Across London, the largest falls in the teenage pregnancy rate were in the boroughs where levels were highest at the start of the 2000s. In Southwark, Wandsworth and Lewisham the rate fell by at ten or more per 1,000 girls aged 13-15. Still, despite seeing the largest fall in Lambeth (from 22.4 to 7.1) it still has the highest rate of any London borough. This is almost 4 times higher than the lowest rate in of 2.1 in Harrow.

It is worth bearing in mind that the rates above are expressed per 1,000, rather than per 100 and averaged across three years, because the actual numbers are quite small. In the borough with the highest number of underage conceptions was Croydon with a total 136 in the three years to 2013.
