Teenage pregnancy rates in the UK are high compared with many other countries but there is marked variation across local areas, including those with high deprivation. This study uses the method of Qualitative Comparative Analysis to identify conditions associated with the presence or absence of a narrowing gap in teenage pregnancy rates as measured by the differences between deprived local authority areas and the national average. A higher proportion of black and minority ethnic groups in the local population is found to be a sufficient although not necessary condition for narrowing to have occurred. Surprisingly, a good assessment of commissioning practice – combined with other conditions – was associated with areas where the gap has not been narrowing.
