More than a quarter of Colorado households, about 430,000, don’t earn enough income to cover basic costs like food, shelter, transportation, health care and childcare, according to a new self-sufficiency standard report Tuesday from the Colorado Center on Law and Policy. Two-thirds of those struggling families don’t meet the official poverty definition, leaving them largely hidden and beyond the reach of programs designed to offer financial support. “Not only do governmental poverty statistics underestimate the number of households struggling to make ends meet, but it creates broadly held misunderstandings about who is in need, what skills and education they hold, and therefore what unmet needs they have,” according to the report, which was prepared by Center for Women’s Welfare at the University of Washington. The study found that 8 percent of Colorado households meet the federal poverty definition, which for a family of two is around $16,460 and below, regardless of the county.
