How have trade/market areas, neighborhoods and other small area geographies changed since 2000? 2010? We develop geographic-demographic-economic data; integrate multi-sourced data for analysis and decision-making; and work with stakeholders to facilitate data access and analysis. We specialize in small area data and difficult to estimate populations. This section provides information on new developments and resources, and direct access to many tools, that can facilitate improved data-driven planning and analysis.

The latest demographic-economic data for census tracts from the American Community Survey (ACS 2017) are estimates centric to mid-2015 for survey respondents over the 5-year period 2013-2017. Updated and extended annually, the ProximityOne annual time series tract estimates-projections are available for the period 2010 through 2024. The scope of subject matter is broader that available from ACS. These data are the best resource for analyzing national scope small area demographic-economic-business characteristics, patterns and change. Corresponding subject matter at the county, metro, state and national levels enable wide ranging geographic comparisons.

About Census Tract Geography and Codes (scroll section)
Census tracts are defined by the Census Bureau and organized as sub-county building blocks. Census tracts are small geographic areas, designed to average 4,000 population, but vary widely. Census tracts cover the U.S. wall-to-wall provide a good geographic granularity to meet many needs. Unchanging throughout the decade, census tract boundaries are subject to update for each decennial census. Major changes occurred with Census 2010 vintage census tracts as the approximate 65,000 Census 2000 census tracts expanded to 73,057 Census 2010 census tracts.

Census tracts were first designed to be relatively homogeneous with respect to population characteristics, economic status, and living conditions. Over time, with demographic shifts, census tracts are often no longer so homogenous. However, tracts do closely approximate neighborhoods/neighborhood parts for many areas. The geographic size of census tracts varies widely depending on the density of settlement. Census tract boundaries are delineated with the intention of being maintained over many decades so that statistical comparisons can be made from decennial census to decennial census. Census tracts may be split due to population growth or combined as a result of substantial population decline.

Census tracts were initially identified by a four-digit basic number and with a two-digit numeric suffix; for example, 6059.02. This version of the tract code is shown in column 3 in the ranking table. The decimal point separating the four-digit basic tract number from the two-digit suffix has been historically shown in printed reports and maps. Many census tracts do not have a suffix; in such cases, the suffix field is either left blank or is zero-filled. Census tract suffixes may range from .01 to .98. These optionally ways of assigning census tract geocodes or handles has led to some vagueness potentially creating problems in handling now common spreadsheet or CSV files.

The national scope uniquely identifying tract geocode is the 11 character code shown in column 4 in the ranking table. The tract geocode is of the form SSCCCTTTTTT where SS is the FIPS state code, CCC is the county FIPS code and TTTTTT is the Census assigned tract code. In the tract geocode, there are never blanks or dots and lead zeroes are used for each the state, county and tract code components. This is the recommended tract unique identifier.

Impact of Census 2010 Census Tract Codes Changes
An important feature of census tract codes and corresponding geographic area is that they typically do not change from one census to the next. The Census Bureau has made changes to some Census 2010 census tract codes and areas in New York following tabulation of the Census 2010 results. ACS 2011 tract estimates, future ACS census tract estimates and non-Census estimates and projections are impacted. These changes impact the structure and number of census tracts in New York and as a result the number and sequencing national scope census tracts. As of Census 2010, there were 73,057 census tracts (states and D.C.); there are now 73,056 census tracts. These changes do not impact tracts/tract data confined to single states other than New York.

For the 2011 ACS data release, there are tract numbering changes and geographic definition changes to census tracts in Madison, Oneida and Richmond counties, New York. The census tract changes in Madison and Oneida Counties are the result of changes to the Oneida American Indian Reservation boundary after the 2010 Census tract definitions had been finalized.

Madison County, New York (36053)
In Madison County, the numbering of nine census tracts changed, but their geographic definitions remain the same as their 2010 census tract definitions.
Census Tract 9401.01 is now 0301.01
Census Tract 9401.02 is now 0301.02
Census Tract 9401.03 is now 0301.03
Census Tract 9402.00 is now 0302.00
Census Tract 9403.00 is now 0303.00
Census Tract 9404.01 is now 0304.01
Census Tract 9404.03 is now 0304.03
Census Tract 9406.00 is now 0306.00
Census Tract 9407.00 is now 0304.02

Oneida County, New York (36065)
In Oneida County, the numbering of three tracts changed, and there is a geographic definition change that affects two tracts.
Census Tract 9400.00 is now 0248.00
Census Tract 9401.00 is now 0247.00

(2010) Census Tract 9402.00 forms a portion of (2011) tract 0249.00
Part of (2010) Census Tract 0230.00 forms a portion of (2011) tract 0249.00
Part of (2010) Census Tract 0230.00 is now (2011) tract 0230.00

Richmond County, New York (36085)
Census Tract 0089.00 merged into Census Tract 0097.00. The area merged into Census Tract 0097.00 is entirely water.

Additional Information
ProximityOne develops geographic-demographic-economic data and analytical tools and helps organizations knit together and use diverse data in a decision-making and analytical framework. We develop custom demographic/economic estimates and projections, develop geographic and geocoded address files, and assist with impact and geospatial analyses. Wide-ranging organizations use our tools (software, data, methodologies) to analyze their own data integrated with other data.
