LSAT has published updated law school application data. As of January 4, 2013, a total of 22,414 people had applied to (ABA accredited) law schools. For comparison sake, this number is 22.1% lower than this point in time last year. Another important fact: last year at this time, we had tallied 42% of what would become the total applicant pool. If that number holds, we would be looking at a total applicant pool around 52,000.
In 2010, 87,900 people applied to law school. As others have noted, this new applicant number of 52,000 would be roughly equal to the number of people who entered law school in 2010.
