The decline in prices outpaced the study in March, which posted losses in 38 of 70 cities, the British Broadcasting Corp. reported Saturday.
A recent study pegged China's gross domestic product as growing 7.5 percent in 2012 with a slowdown partly attributed to lower property prices.
Some analysts, the BBC said, consider 8 percent the breaking point. With 8 percent growth or above, China can continue to increase jobs, invest in infrastructure projects and support domestic demand. In so many words, with 8 percent GDP growth, China can continue to expand its middle class.
In January through March 2012, China's GDP grew at an annual pace of 8.1 percent.
