The United States Census Bureau released two new studies of school statistics today.

One is School enrollment 2012.  Highlights of the document include: --In 2012, 78 million people, or 26.4 percent of the population 3 or older, were enrolled in school. 

--In 2012, there were 19.9 million college students, including 5.8 million enrolled in two-year colleges, 10.3 million in four-year colleges and 3.8 million in graduate school.
--In 2012, there were 4.2 million students enrolled in private elementary and high schools (first through 12th grade), down from 4.8 million in 2005. 

--Non-Hispanic white children in 2012 comprised 53 percent of elementary school students, down from 58 percent in 2005. Hispanic children made up 24 percent of elementary students in 2012, up from 20 percent in 2005. Black children comprised 15 percent of elementary students in 2012, down from 16 percent in 2005. 

--Students who were born in another country or whose parents were foreign-born comprised 32 percent of all those enrolled in school at all levels in 2012. 
--While most students are under 25, there were 804,000 students age 50 and older enrolled in schools at all levels in 2012. You can review the tables here.

The other is School Enrollment in the United States - 2011.  Highlights include:

6% of students aged 6 to 21 in public schools have a disability.  

NOTE: the American Community Survey uses a very different definition of "disability" than does IDEA.  The condition of Education study done by the department of Education's National Center for Education Statistics found that 13% of public school students  in 2012 have a disability as defined by IDEA.
