The chief sources of revenue upon which the State depends are taxes on corporations, automobile licences and fees, the gasolene tax, inheritance tax and anthracite coal tax. In general it is the policy to leave the general property taxes to the counties and smaller units. Almost one-half of the State income is used for the two items, highways and education. The State debt on Dec. 31, 1931, amounted to $89,978,000, of which $89,221,000 was for highway purposes.
On June 30, 1934, the total number of commercial and savings banks was 14 1, with total resources and liabilities of $5,272, 784,000, capital, surplus, and undivided profits of $843,650,000, and deposits of $3,655,469,000.

The total enrolment of these was 8,389 students, their combined teaching staffs numbered 674. Pennsylvania's established minimum of preparation required of teachers in the elementary schools is the completion of a four-year high school course and not less than two years of professional preparation or its equivalent.

Annual salaries of all teachers, supervisors, and principals in the public school system averaged $1,630 in 1932 as against $920 in 1920.
The establishment of evening classes and classes in English and citizenship for adults has helped to bring down the ratio of illiteracy from 5.9% in 1910 to only 3.1% in 1930, in which year 15.4% of the foreign-born whites, 4.2% of the negroes, and
0.6% of the native whites were unable to read or write.
