*Total population figure derived from Greater London Authority age-range creator for Office for National Statistics (ONS) mid-year population estimates covering 2014; this source also provided population age group frequencies and proportions. These files take into account the revised estimates for 2002–2010 released in April 2013 down to Local Authority level and the post 2011 estimates based on the Census results. Ethnicity population frequencies and proportions derived from ONS ethnicity data which are based on 2011 Census results only; total number of females of reproductive age according to these data is lower (n=1 61 658).
†Service-users self-selected ‘prefer not to say’.
‡Frequencies and proportions of LSOAs per IMD quintile derived from Ministry of Housing, Communities & Local Government IMD data (2015) (n=344).
§Missing data for three observations for IMD.
COC, combined oral contraceptive pill; IMD, Index of Multiple Deprivation; LSOA, Lower-layer Super Output Area; OCP, oral contraceptive pill; POP, progestogen-only pill.
