In 2012/13 English councils launched 127,060 high-level investigations - known as section 47s - into children thought to be at risk, analysis of official figures shows.
That is the equivalent of one in 100 of the country's entire population of under-18s and represents a 42.3% increase in cases since 2009/10.
In some areas the figure is much higher with the equivalent of 4.5% of children in Blackpool, 2.6% in Doncaster and 2.1% in Peterborough being investigated.
Experts said the significant increase in suspected abuse cases could be explained by the heightened awareness of the issue following the tragic case of Baby Peter Connelly in 2008.
However, they also said the impact of the recession on households had led to a marked rise in ill treatment of children.
The figures follow a series of high-profile cases of child abuse including that of four-year-old Daniel Pelka who was starved, tortured and brutally beaten to death by his mother and stepfather.
Dosent matter if your gay or straight there will always be sick people out there who wish to do children harm. My earlier comments where my opinion of gay adoption and i can accept and understand other peoples opinions why gay couples shouldnt adopt. What i cant stand is blatant homophobia for the sake of it which certain people felt the need to hijack this post with.
