A square, or portion of a city inclosed by streets, whether occupied by buildings or not.
A section of a railroad where the block system is used. See Block system, below.
A unit of spatial aggregation used by the U. S. Bureau of the Census in reporting decennial census data, corresponding roughly to its colloquial meaning.
Small areas bounded on all sides by visible features such as streets, roads, streams and railroad tracks and by invisible boundaries such as cities, towns, townships, county limits and property lines. Blocks are numbered uniquely within each census tract or block numbering area. A Block is identified by a three-digit number, sometimes with a single alphabetical suffix.
Platted lots; normally bounded by public streets.
In prototype railroading, a section of track through which rail traffic is controlled as a unit. In model railroading, commonly the designation for a length of track with an independently controlled power supply, constructed so two or more trains may operate independently on, for example, a simple oval of track.
A geographic area bounded on all sides by visible or nonvisble features shown on census maps. A block is the smallest geographic entity for which the Census Bureau collects and tabulates decennial census information.
on a real railroad, a section of track defined for the purpose of controlling trains. On a model railroad, a block is an electrically isolated section of track.
Normally a rectangular piece of land, bounded by four streets. However, a block may also be irregular in shape or bounded by railroad tracks, streams, or other features. Blocks do not cross the boundaries of counties, census tracts or block numbering areas (BNAs). Census data are tabulated by block in all urbanized areas but much information is suppressed to protect the confidentiality of census information. A block is the smallest level of census geography.
A unit of property entirely surrounded by public highways, streets, railroad rights-of-way, waterways or other barriers, or some combination of these boundaries.
A section of railroad track that is isolated from adjacent track. A block may simply be a geographic location, or a section of trackage that is equipped with block signals.
Block An individual area of land which is usually enclosed by city streets. Each block is assigned a unique identification number by the Department of Finance.
a square or portion of a city enclosed by streets, whether it is occupied by buildings or comprised of vacant lots. In addition, blocks are often enclosed by the boundary of a subdivision.
A designated area on a section map preferably bounded by natural boundaries such as streets, roads, waterways or other prominent features.
A subdivision of a census tract (or, in 1990, a block numbering area), a block is the smallest geographic unit for which the Census Bureau tabulates 100-percent data. Many blocks correspond to individual city blocks bounded by streets, but blocks -- e specially in rural areas may include many square miles and may have some boundaries that are not streets. The Census Bureau established blocks covering the entire nation for the first time in 1990. Previous censuses back to 1940 had blocks established onl y for part of the nation. (Due to confidentiality requirements, American Community Survey data cannot be viewed on a single block level; the smallest geographic group available for public use is the Block Group.)
A piece of land usually bounded on all sides by streets or other transportation routes such as railroad lines, or by physical barriers such as bodies of water or public open space, and not traversed by a through street. Often used as part of a subdivision legal description.
A piece or parcel of land entirely surrounded by public highways, streets, streams, railroad rights-of-way or parks, etc., or a combination thereof.
A square or rectangular portion of a city or town enclosed by streets. Often used as part of a subdivision legal description.
A subdivision of a census tract (or, prior to 2000, a block numbering area), a block is the smallest geographic unit for which the Census Bureau tabulates 100-percent data. Many blocks correspond to individual city blocks bounded by streets, but blocks - especially in rural areas - may include many square miles and may have some boundaries that are not streets. The Census Bureau established blocks covering the entire nation for the first time in 1990. Previous censuses back to 1940 had blocks established only for part of the nation. Over 8 million blocks are identified for Census 2000. Related terms: 100-percent data, Census block, Census geography, Census tract
