3-26 UA Census 2000 TIGER/Line® Files

Census Feature Class Codes (CFCCs)

A census feature class code (CFCC) is used to identify the most noticeable

characteristic of a feature. The CFCC is applied only once to a chain or

landmark with preference given to classifications that cover features

that are visible to an observer and a part of the ground transportation

network. Thus, a road that also is the boundary of a town would have a

CFCC describing its road characteristics, not its boundary characteristics.

Attributes of Geographic Objects 3-27

The CFCC, as used in the TIGER/Line® files, is a three-character code.

The first character is a letter describing the feature class; the second

character is a number describing the major category; and the third

character is a number describing the minor category.

Some street features in the UA Census 2000 TIGER/Line® files that normally

would be classified as "A" class features may now be coded with a

"P’ instead of the "A" to indicate that the feature is a "provisional" feature.

The numeric portion of the CFCC still classifies the street as if an "A" were

preceding it. Provisional features are those streets that were added from

reference sources or other programs in preparation for Census 2000, but

were not field verified by census staff during field operations or through

the use of aerial photography or imagery. As these features are verified in

future operations the provisional flag will be removed for subsequent

TIGER/Line® file releases. Features that still have the provisional flag at

the time the U.S. Census Bureau assigned the Census 2000 tabulation block

numbers were not held as Census 2000 tabulation block boundaries.

Feature Class A, Road

The U.S. Census Bureau uses the term divided to refer to a road with

opposing traffic lanes separated by any size median, and separated to

refer to lanes that are represented in the Census TIGER® database as two

distinct complete chains.

The term, rail line in center, indicates that a rail line shares the road rightof-

way. The rail line may follow the center of the road or be directly next

to the road; representation is dependent upon the available source used

during the update. The rail line can represent a railroad, a streetcar line,

or other carline.

Primary Highway With Limited Access Interstate highways and some toll

highways are in this category (A1) and are distinguished by the presence

of interchanges. These highways are accessed by way of ramps and have

multiple lanes of traffic. The opposing traffic lanes are divided by a

median strip. The TIGER/Line® files may depict these opposing traffic

lanes as two distinct lines in which case, the road is called separated.

and regionally important highways that do not have limited access

as required by category A1. It consists mainly of US highways, but may

include some state highways and county highways that connect cities and

larger towns. A road in this category must be hard-surface (concrete or

asphalt). It has intersections with other roads, may be divided or undivided,

and have multi-lane or single-lane characteristics.

Local, Neighborhood, and Rural Road A road in this category (A4) is used

for local traffic and usually has a single lane of traffic in each direction. In an

urban area, this is a neighborhood road and street that is not a thoroughfare

belonging in categories A2 or A3. In a rural area, this is a short-distance

road connecting the smallest towns; the road may or may not have a state or

county route number. Scenic park roads, unimproved or unpaved roads,

and industrial roads are included in this category. Most roads in the Nation

are classified as A4 roads.

in very rural areas. Sometimes the road is called a fire road or

Landmark is the general name given to a cartographic (or locational)

landmark, a land-use area, and a key geographic location (KGL). A

cartographic landmark is identified for use by an enumerator while

working in the field. A land-use area is identified in order to minimize

enumeration efforts in uninhabited areas or areas where human access

is restricted. A key geographic location is identified in order to more

accurately geocode and enumerate a place of work or residence.

Feature Class P, Provisional Features

The U.S. Census Bureau has created a new CFCC type that may appear

on street features only. Some streets that normally would be classified as

"A" class features may be coded with a "P" instead of the "A" to indicate

that the feature is a "provisional" feature. Provisional features are those

streets that were added from reference sources or other programs in

preparation for Census 2000, but were not field verified by census staff

during field operations or through the use of aerial photography or

imagery. As these features are verified in future operations the provisional

flag will be removed for subsequent TIGER/Line® releases. The

numeric portion of the CFCC still classifies the street as if an "A" were

preceding it.

Feature Class X, Not Yet Classified

Classification Unknown or Not Elsewhere Classified

CFCC Description

X00 Feature not yet classified

All complete chains, landmarks, and key geographic locations have a

code representing their census feature class. Only those GT-polygons

associated with an area landmark have a CFCC. Most CFCCs in the

feature classification scheme apply only to complete chains. In a few

instances, the same feature code may apply to complete chains as well

as to point and area landmarks.

Only those features required for census operational purposes are classified

and inserted into the Census TIGER® database. Therefore, not all features

in a county will appear in the TIGER/Line® files. Since features are classified

with only a single code, a road that also is a boundary will have only

the CFCC of a road even though a CFCC for a boundary exists in the

classification scheme.
