It is estimated that the number of women unable to access family planning rose by one fifth during lockdown, to 3,688,000.
The projections, by the University of the Philippines Population Institute and the United Nations Population Fund (UNFPA), suggest that an additional 214,000 babies could be born next year as a result of unplanned pregnancies caused by the pandemic.
This means there could be up to almost 1.9 million births in 2021, more than in any year since 2000.
