The estimated population of the Raleigh-Durham-Cary CSA was 1,635,974 as of July 1, 2007, with the Raleigh-Cary Metropolitan Statistical Area (MSA) portion estimated at 1,047,629 residents.
Most of Raleigh is located within Wake County, with a very small portion extending into Durham County. The towns of Cary, Garner, Wake Forest, Apex, Holly Springs, Fuquay-Varina, Knightdale, Wendell, and Rolesville are some of Raleigh's primary nearby suburbs and satellite towns.

Raleigh-Durham International Airport, the region's primary airport and the second-largest in North Carolina, located northwest of downtown Raleigh via Interstate-40 between Raleigh and Durham, serves the city and greater Research Triangle metropolitan region, as well as much of eastern North Carolina. The airport is a hub for American Eagle Airlines. The airport offers service to more than 45 domestic and international destinations and serves approximately 10 million passengers a year. The airport also offers facilities for cargo and general aviation. The airport authority currently is tripling the size of its Terminal 2 (formerly Terminal C), and is planned for completion in winter of 2011.
Several licensed private general-aviation airports operate in Raleigh's immediate suburban areas:
Raleigh's train station is one of Amtrak's busiest stops in the Southern U.S. The station is served by three passenger trains, the Silver Star, Piedmont, and Carolinian. Daily service is offered between Raleigh and:
Public transportation in and around Raleigh is provided by Capital Area Transit (CAT), which operates 38 bus fixed routes and a historic trolley line within the city, and also by Triangle Transit (known formerly as the Triangle Transit Authority, or TTA). Triangle Transit offers scheduled, fixed-route regional and commuter bus service between Raleigh and the region's other principal cities of Durham, Cary and Chapel Hill, as well as to and from the Raleigh-Durham International Airport, Research Triangle Park and several of the region's larger suburban communities. TT also coordinates an extensive vanpool and rideshare program that serves the region's larger employers and commute destinations. North Carolina State University also maintains its own transit system, the Wolfline, that provides free bus service to the general public along multiple routes serving the university's campuses in southwest Raleigh.
Government agencies throughout the Raleigh-Durham metropolitan area have struggled with determining the best means of providing fixed-rail transit service for the region. Triangle Transit developed a plan for constructing a self-propelled, diesel-fueled commuter rail system along existing freight rail corridors within the region. Due to low ridership projections and fiscal constraints, this plan was recommended for denial of matching federal funds by the Federal Transit Administration (FTA) in 2006. The region's two metropolitan planning organizations appointed a group of local citizens in 2007 to reexamine options for future transit development in light of Triangle Transit's problems. The Special Transit Advisory Commission (STAC) retained many of the provisions of Triangle Transit's original plan, but recommended adding new bus services and raising additional revenues by adding a new local half-cent sales tax to fund the project.
The mountains-to-the-sea North Carolina Bicycle Route 2 travels through the city of Raleigh, as does the Maine-to-Florida U.S. Bicycle Route 1. North Carolina Bicycle Route 5, the Cape Fear run, connects nearby suburban Apex to the coastal city of Wilmington, North Carolina, and closely parallels the route of the Randonneurs USA (RUSA) 600 km brevet route. .
Most public buses are equipped with bicycle racks, and some roads have dedicated bicycle-only lanes. Bicyclists and pedestrians also may use Raleigh's extensive greenway system, with paths and trails located throughout the city.
