PwC and Partnership for New York City (2012). Cities of opportunities, http://www.pwc.com/us/en/cities‐of‐opportunity/2012/pdf‐download.jhtml The indicators below were used for 2011. Table R.1 – PwC: Cities of opportunities index Air pollution Measurement of the quality of a city's air based on the degree of pollution from sources such as vehicles and power plants. Aircraft movements Count of air traffic movements at each of the major airports servicing a city, including civil international and domestic passenger, cargo and non‐revenue flights but excluding military flights. Airport to CBD access Measure of the ease of using public transit to travel between a city's central business district and the international terminal of its busiest airport in terms of international passenger traffic. Cities are separated into categories according to whether a direct rail link exists between the city center and the airport – if so, the number of transfers required, and if not, whether there is a public express bus route to the airport. Cities with direct rail links are preferred to those with express bus services. Cities with rail links with fewer transfers are ranked higher than those with more. Cities are ranked against other cities in the same category according to the cost of a single one‐way, adult weekday trip and the length of the trip, with each factor weighted equally.
