These Period Poverty facts/statistics are from the UK but I imagine the situation is similar in other countries (and maybe worse in some).
Over 10% of girls and women in the UK struggle to afford sanitary products every month. This figure is considerably higher among the homeless and refugee communities.
Approximately 100,000 girls miss time at school every year because they are unable to access or afford sanitary products. This leads to reduced educational attainment and lower life opportunities.
Poor menstrual hygiene, along with the use of inadequate sanitary products, or using them for too long, can cause infections and other health issues, including urinary tract infections and Toxic Shock Syndrome.
It is estimated that women in the U.K. spend more than £15,000 due to their period across their lifetime.
Sanitary products are an essential, not a luxury.
