The blue pies show the percentage of poor people in each country, defined by whether they have electricity and the type of floor they have in their home. Bangladesh has a much higher fraction of poor people than India.
The green pies show the sanitation practice of the majority of the poor in each country. In India, the majority of the poor defecate in the open, while in Bangladesh the majority of the poor use a toilet or latrine.
Thus, despite being poorer, Bangladeshi households use latrines.
