ZIPN 2004 ZIP code (numeric)
ZIPA 2004 ZIP code (alpha with leading zeros)
RUCA2 RUCA 2.0 code (e.g., 10.3 or 4.0)
ZIPTYP ZIP Type (1=residential (30,096), 2= commercial (11,832))
PARZIP Residential ZIP if “2” for RUCA Type (ZIPTYP) -- if ZIP is commercial this field holds the parent numeric residential ZIP code in which it is located; if ZIP is residential it contains the same ZIP as in ZIPN
LINF1 Flag indicating that linear distance between the ZIP and the nearest edge of a 1 was used because roads did not directly connect the two ZIP population centroids (e.g., islands, ferries, not roads for remote places in Alaska etc.) (1= yes (312) , 2= no (25,120), -1= NA (not applicable) (16,496)). NAs are ZIP codes with RUCA codes of 1.0 and 1.1.
LINF4 Flag indicating that linear distance between the ZIP and the nearest edge of a 4 was used because roads did not directly connect the two ZIP population centroids (e.g., islands, ferries, not roads for remote places in Alaska etc.) (1= yes (231) , 2= no (22,471), -1= NA (19,226)). NAs are ZIP codes with RUCA codes of 1.0, 1.1, 4.0, 4.1, and 4.2).

STATE State alpha two-digit state abbreviation where the majority of the population resides (e.g., CA= 2,717) . USPS state abbreviations.
MST Flag that indicates whether a ZIP crosses a state boundary and the alpha two-digit state abbreviation of the overlapping state ( there are 6 ). Otherwise the field is blank.
UUSZ This variable is not yet available – work in progress currently (-9s in column) 2000 population of the Census Bureau defined urban unit (i.e., Urbanized Area, Urban Cluster, and Census Rural if less than place of 2,500) in which the ZIP code resides (approximated from Census tracts): (1=<2,500; 2=2,500-4,999; 3=5,000-9,999; 4=10,000-19,999; 5=20,000-29,999; 6=30,000-49,999; 7=50,000-99,999; 8=100,000-249,999; 9=250,000-499,999; 10=500,000-999,999; 11=1,000,000-1,999,999; 12=2,000,000 and higher) (see Data: Urbanized Area and Urban Cluster Populations section)

ZIPPOP 2004 population estimate: (1=zero, 2=1-99, 3=100-499, 4=500-999, 1000 and higher) – commercial ZIPs will always show zero population (2004 populations estimates provided by Claritas Inc.). In addition, 152 other ZIP code areas have a population estimate of zero.

Notes:

  1. NA= not applicable
  2. For all variables, “-1” is not applicable and “-9” is used when the data are missing/not available.
  3. Many of the variables are not available for Puerto Rico.
  4. Travel times and distances are one-way along the route determined to be the fastest route to the closest named place type on paved roads. Distances and times are calculated from the population centroid of the origin ZIP code area to the population centroid of the potential destination ZIP code areas. The information provided represents the travel time and distance to the nearest centroid of the type indicated (e.g., code 1.0 or 1.1). Travel time and distance for variables (i.e., TTIM1A, TTIM4A, TDIS1A, TDIS4A, TTIM1B, TTIM4B, TDIS1B, and TDIS4B) are assigned zero when they are within their type (e.g., travel time to the nearest 1.0 when the ZIP is a 1.0). They are assigned a -1 when it is not applicable (e.g., no times or distances for 1.0s and 1.1s to 4s). Of course, the travel times and distances can be combined to show nearest travel time and distance to 1s and 4s (i.e., closest one looking at both types of destinations). In such cases, the -1s assigned for the 1s (relative to the 4s) would be recoded to zeros for the comparisons.

There are 41,928 cases in the national file. Individual state files contain the following number of cases:
