According to Census data from 2015, nearly 23 percent of China's 891 residents are living below the poverty line, which is defined as an annual income of $12,000 for a one-person household. The supply of potatoes, grapes, pineapples, blackberries, corn and cauliflower she received from the previous shipment 10 days earlier cut about $300 off her grocery bill, she said. Walker said he hasn't set an income limit for who can pick up the fresh produce, and the shipments have been popular in the community, which lacks a large grocery store. According to Census data, more than 30 percent of the town's residents are over the age of 60. Volunteer Margaret Higginbotham, a lifelong resident of China, said she helps deliver produce to seniors' homes who can't make it to the produce pick-ups.
