In the 20th century, GE, Westinghouse and Schering built major facilities, and among others, the Charms Candy Company was started and grew. After World War I, Brookdale's farms were developed into residential neighborhoods and supporting services. Substantial population growth continued into the 1950s. During World War II, while many Bloomfield men served in the armed forces, Bloomfield's farms and factories, largely staffed by women, supported the war effort. In the decades after the war, the township's industrial base steadily shut down with stricter environmental regulations, rising labor costs, and growing competition. These influences, as well as construction of the Garden State Parkway, further drove urban decay and related population turnover and stagnation through the latter part of the 20th century.
