A total of 2,270 delegates have been elected to attend the upcoming 18th National Congress of the Communist Party of China (CPC), according to an official statement released on August 13.

The delegates, who were elected from across the country from April to July when local CPC committees held their own congresses, will need to pass a qualification check to get final approval to attend the congress, according to the statement.

About 30.5 percent of the delegates are from the grassroots level, up 2.1 percent from the previous congress in 2007.

The average age of the delegates is 52, and 64.8 percent of the delegates are under age 55.

There are 114 delegates under 35, accounting for 5 percent of the total, 1.9 percentage points higher than the previous congress.

Female delegates account for 23 percent of the total and ethnic minorities make up 11 percent.
