Q: Labor unions generally ignored government employees because they were controlled mostly by the patronage system used by the political parties before the arrival of civil service. Post Office workers did form unions. The National Association of Letter Carriers started in 1889 and grew quickly. By the mid-1960s it had 175,000 members in 6,400 local branches. Several competing organizations of postal clerks emerged starting in the 1890s. Merger discussions dragged on for years, until finally the NFPOC, UNMAPOC and others merged in 1961 as the United Federation of Postal Clerks. Another round of mergers in 1971 produced the American Postal Workers Union . In 2012 the APWU had 330,000 members. The various postal unions did not engage in strikes.
How many years after the formation of the United Federation of Postal Clerks did the American Postal Workers Union form?

Q: According to the FBI, a city to city comparison of crime rates is not meaningful, because recording practices vary from city to city, citizens report different percentages of crimes from one city to the next, and the actual number of people physically present in a city is unknown.

(14.48), Kansas City, Missouri (14.44) and Boston (13.39). However, Houston (11.69), Los Angeles (7.87), and New York City (6.38) have lower violent crime rates than Dallas.

Q: Charleston, North Charleston, Goose Creek, and Hanahan are home to branches of the United States military. During the Cold War, the Naval Base became the third largest U.S. homeport, with 23,500 Navy and Marine personnel, and 13,200 civilians serving over 80 ships and submarines. In addition, the combined facilities of the Naval Base and Weapons Station created the largest U.S. submarine port. The Charleston Naval Shipyard repaired frigates, destroyers, cruisers, submarine tenders, and submarines. Also during this period, the shipyard conducted refueling of nuclear submarines. The Weapons Station was the Atlantic Fleet's loadout base for all nuclear ballistic missile submarines. Two SSBN "Boomer" squadrons and a submarine tender were homeported at the Weapons Station, while one SSN attack squadron, Submarine Squadron 4, and a submarine tender were homeported at the Naval Base. At the 1996 closure of the station's Polaris Missile Facility Atlantic , over 2,500 nuclear warheads and their UGM-27 Polaris, UGM-73 Poseidon, and UGM-96 Trident I delivery missiles were stored and maintained, guarded by a U.S. Marine Corps security force company.
