A new report reveals that last year, one out of four Californians had no health insurance coverage.

According to the investigators from UCLA's Center for Health Policy Research, the number of uninsured people in the province rose to around 8.2 million in 2009, as compared to 6.2 million in 2007. Around 24.3% people aged 65 had no health insurance.

The rate of uninsured children in the state increased to 13.4% in 2009 in comparison with 10.2% in 2007. The number of the state’s uninsured children climbed from 1.1 million to 1.5 million over the past two years.

Due to lack of the health insurance coverage, many poor Californians have not been provided proper medical care as they need to bear heavy expenses of the hospitals. Hospitals and insurance companies often bear some of the expenses of customers with health insurance.

The state of California has a large population, as a result it includes highest number of uninsured people in the country.

"Being uninsured has real human consequences. . . . It is costly for all of us. It makes reforms of the system absolutely essential”, said Shana Alex Lavarreda, Director of Health Insurance Studies at the UCLA research center.
