Bars on Fields Avenue catering to the single American defense personnel, who worked in the adjacent Clark Air Base, first emerged in 1940.
[3] This led to a proliferation of bars, live bands and prostitution, the latter mostly by young Filipina women, most of them either teenagers or 18–55 years old.
[4] This led to a mushrooming of related ancillary industries in the vicinity, namely music bands, hotels, doctors, hairdressers and money exchange / transfer services.
As Clark was turned into a Special Economic Zone (SEZ), these bars and prostitution joints changed their clientele to suit their new customers - Japanese and Korean businessmen.
[11] People arriving by air either take a taxi direct to hotel or a jeepny to Main Gate Jeepney Terminal located between to north SM mall, Fields Avenue to south and Bayanihan Park to east.
[12] Fields Avenue remains among the safest streets in the region, with a very low crime rate, exceptionally few robberies, fights or murders.
Most Filipino and international fast food chains including McDonald's, KFC and Jollibee have at least one branch along or near Fields Avenue.
