CHARLOTTE-- The United State Postal Service says First Class mail volume is down nearly 61 percent nationwide over the last 20 years.

A new postal service report says the decline is greater in urban areas than rural, though they don’t offer an explanation why.

USPS says now they'll study what they'll do to adjust.

UNC Charlotte Associate Political Science Professor Zach Mohr says doing away with the mail altogether isn't an option.

“The only service the Constitution says the federal government must provide is post office and post roads,” he said.

Mohr also offered a solution, noting the rise of Internet shopping: “The USPS really has an opportunity here to shift from letters to let's say packages.”

First Class mail is down in North Carolina about 58 percent.

Mohr says the decline has accelerated in the last 10 years.
