Postpartum Depression (PPD) affects women during pregnancy or within a year of giving birth. This paper uses data
science principles to study the prevalence of PPD in women from the state of Bihar in India. Data was obtained by trained
surveyors for a random sample of 531 women, aged 15 to 41 years old, who had been pregnant or recently given birth. Our
results show a significant occurrence of PPD in the population with 24% ± 4% of women showing symptoms based on a 95%
confidence interval.
