Texas officials haven't requested much new money in the upcoming state budget for Children's Health Insurance Program that insures children from working-poor families because they predict it will barely grow, even as the economy sours and the state population swells. Advocates for low-income families, though, are skeptical that there will be little or no enrollment growth in CHIP. Though enrollment in Texas soared to nearly 477,000 in August, from 300,000 a year ago, the Texas Health and Human Services Commission says it believes growth will slow to a crawl.
