Children growing up in lesbian, gay, bisexual and transgender families in the US are more likely to live in poverty and may be denied legal ties to one of their parents, a report showed.
A lack of federal recognition of same-sex marriages means such families face higher tax burdens and unequal access to health insurance and government safety net programmes, said the report entitled All Children Matter: How Legal and Social Inequalities Hurt LGBT Families.
The report, by groups advocating for gay rights including Movement Advancement Project, Family Equality Council and Centre for American Progress, was released online.
"The reality is if you look at today's modern families, they come in all shapes and sizes," said Jennifer Chrisler, executive director of Family Equality Council.
"The laws and policies we have in place haven't kept pace with that changing reality."
