Literacy rate is the amount of people who can read and write any one language at the least and standard of living is a level of material comfort which is observed by goods, services, luxuries offered to an individual or a nation.
the higher the literacy rate, higher is the standard of living, which in turn helps to increase the economic success and the Gross Domestic Product(GDP) of the country
The map is pointing to the middle colonies, but the middle colonies consisted of PA, NJ, Delaware etc, but the arrow is specifically on New Jersey so I would assume New Jersey.
