Average personal income rose slightly more in Maryland last year than in the nation as a whole, but not as much as in 2011, the U.S. Department of Commerce said Wednesday.

Maryland personal income increased 3.6 percent on average last year, compared with a gain of nearly 5 percent in 2011. Nationwide, the figure rose 3.5 percent last year versus 5.2 percent growth the year before.

Personal income includes all sources of money flowing to residents, from paychecks to interest payments to Social Security. Per person, Maryland has the fifth-highest personal income in the country — about $52,000. Connecticut is No. 1, at nearly $59,000.

Close on Maryland's heels is North Dakota, which has seen the country's biggest gains in personal income for five of the last six years. That state's boom in oil and natural gas production helped push its average to nearly $52,000 per capita — up from $27,000 a decade earlier.
