⁽¹⁾ Cluster level education is based on the mean years of educational attainment of the population in the neighbourhoods: – urban: low (9.0–10.5), middle (10.6–11.0), high (11.1–11.3)

⁽²⁾ Individual level education categorization is as follows: urban: low (grade 0 – 7), middle (grade 8 – 11), high (grade 12 and above)

⁽³⁾ CI, confidence interval

⁽⁴⁾ AOR, age-adjusted odds ratio

⁽⁵⁾ '0 partner' is equal to the number young women who have not had sexual intercourse

Significant results are in bold (p < 0.05)
