Data in
NEO CANDO are available at several levels of aggregation including census
geographies and locally defined geographies. Descriptions of each of the
different aggregations are provided below. First, described are the census
geographies included in NEO CANDO. Second, we describe locally defined
geographies. For more detailed information about the census geographies click here.
All of the data in NEO
CANDO is based on 2000 tract boundary definitions. For data we receive at
the address level, we geo-coded the data into the 2000 census geography. For
the Census data, we used GIS techniques to convert 1990 census data into the 2000
census geography. Data should be in the same geographic boundaries to allow
for accurate comparison over time. Census tract level
data are available for the following 17 counties: Ashland, Ashtabula,
Columbiana, Cuyahoga, Erie, Geauga, Huron, Lake, Lorain, Mahoning, Medina, Portage, Richland, Stark, Summit, Trumbull, and Wayne.
Keep in mind that some
census tracts have changed numbers, split, or changed physical boundaries over
the decade. So a tract that existed in 1990 may not exist in 2000, the tract
number may have changed or the physical boundaries may have changed. In order
to accurately compare data over time the data should be in the same geographic
boundaries. We ensure the user is comparing apples to apples by
converting all of our data into the same geographic boundaries -- 2000 geography.
However, other sites may have 1990 data in the 1990 geography. We caution the
user that counts based on 1990 geography will yield different counts than those
based on 2000 geography. The user should not compare data in the 1990 geography
to data in the 2000 geography.
CENSUS GEOGRAPHIES
Census Block
Census blocks are the
smallest census geography. Generally, a census block is a street block. Blocks
are subdivisions of both census block groups and census tracts. Census blocks
are bounded on all sides by visible features such as streets, roads, streams,
railroad tracks and invisible features such a city boundaries or county
boundaries. There are 14,775 census blocks in Cuyahoga County.Census blocks numbers consist
of 10 digits, for example 1011.00-1000.
Census Block Group
Census block groups are
clusters of census blocks and have the same first four digits of a census tract.
Census block groups do not cross census tracts but may cross other geographic
boundaries. Block groups contain between 600 and 3000 people. There are 1261
block groups in Cuyahoga County. Census block groups consist of 7 digits, for
example 1011.00-1.
Census Tract
Census tracts are small
statistical subdivisions of a county. They usually have between 2,500 and
8,000 persons and are designed to be homogeneous in terms of population
characteristics, economic status, and living conditions. There are 505 census
tracts in Cuyahoga County and 225 in the City of Cleveland. Census tracts
are identified by a four-digit number and may have a two-digit suffix, for
example, 1011.01.

City, village and MCD (minor civil
division)
This level of geography
contains the data for the cities, villages and townships in each of the 17
counties. The Census Bureau defines cities/villages/townships as places and/or county
subdivisions/minor civil divisions (MCD). Minor civil divisions are generally
townships and cities while places are either cities or villages. The place/MCD
level has been split into cities, villages and townships in NEO CANDO.
Particularly in more rural counties, townships consist of parts of different
villages and/or cities.
County
This geographic level
provides data for the County as a whole. There are 88 counties in Ohio. The map highlights
the 17 counties for which we have data in NEO CANDO. The counties of Ashtabula, Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and Summit comprise the Cleveland-Akron
Metropolitan Area.
LOCALLY DEFINED GEOGRAPHIES
Neighborhood
Neighborhoods in NEO
CANDO refer to both the Statistical Planning Areas (SPAs) and the suburban
municipalities. This geographic level is ONLY available for Cuyahoga County in NEO CANDO. The SPAs are geographic areas
that were defined by the City of Cleveland Planning Commission in conjunction
with community organizations and residents. The SPAs are a combination of
contiguous census tracts within the City. The SPAs were defined based on
generally accepted neighborhood boundaries within each area and compatibility
with census tract boundaries. There are 36 SPAs in the City of Cleveland. These SPAs are NOT census geography; therefore, the user is unable
to extract data from the Census Bureau's web site based on these areas.
The user must extract data by census tract and aggregate to the SPA
level. The suburban municipalities of Cuyahoga County (i.e. Lakewood, East Cleveland) are
census geography and can be extracted from the Census Bureau's web site.
There are 58 suburban municipalities in Cuyahoga County.
Neighborhood by Census Tract
Neighborhood by census tract provides the user with a breakdown of data by census tract within the
neighborhood (SPA) or municipality. All neighborhoods and municipalities
consist of a number of census tracts. The number of census tracts will
vary by neighborhood/municipality. To choose only the census tracts
within the City of Cleveland, the user must use the census tract geographic
level and choose all the tracts with tract numbers less than 1300.00. All
tracts with numbers greater or equal to 1300.00 are within the suburban
municipalities. The Neighborhood by Census Tract may be particularly useful for
targeting program services to an area within a neighborhood that may benefit
from the most.
There are some census tracts that cross municipality boundaries. We account for this in our counts.
For example, tract 1939.00 crosses the city of Warrensville Heights and the
city of Highland Hills. There is a population of 1,747 in tract 1939.00 -- 129
of that population resides in Warrensville Heights while the remaining 1,618
resides in Highland Hills. When choosing the neighborhood by census tract for Warrensville Heights, the user will get only the portion of the census tract population
that resides in Warrensville Heights. Here is a complete list of the census tracts in Cuyahoga County that cross municipality boundaries.
| 2000 Census Tract | Neighborhood | Population |
| 1342.03 | Berea | 2,379 |
| Olmsted Falls | 11 |
| 1905.04 | Olmsted Falls | 513 |
| Olmsted Township | 5,924 |
| 1939.00 | Warrensville Heights | 129 |
| Highland Heights | 1,618 |

DCFS Geo-districts
Cuyahoga County is divided into nine geographic
districts for the purpose of assigning Department of Children and Family
Services (DCFS) staff to ongoing child welfare cases. Ongoing cases are cases
that, following an investigation of child maltreatment report, included a
determination that the family should receive some services while the children
remain at home, or that the children should be placed in foster care. Under
this system, a specific unit of DCFS staff is assigned to serve all the cases from
each specific area. Geographic assignment of these cases helps the DCFS staff
become more knowledgeable about the neighborhoods where they work and
neighborhood residents benefit from getting to know
the DCFS staff who serve their community. For the most part, the DCFS geographic
districts are comprised of contiguous neighborhoods and suburban
municipalities.
Cleveland Wards
Cleveland wards are the 21 political
boundaries in the City of Cleveland updated in 2001. Each ward is represented
by a council person.
Strategic Investment Iniative Areas
The Strategic Investment Iniative Areas, or SIIs, are smaller target areas within the
boundaries of six specific neighborhoods where the local CDC has joined with
Neighborhood Progress Inc. to leverage a broad array of resources and investments
designed to stimulate real estate market recovery.
Buckeye-Fairwood Zone
Zones delineated in the Buckeye and Fairwood (Larchmere) Neighborhoods of Cleveland for a focused
comprehensive planning effort jointly sponsored by Buckeye Area Development
Corporation, Shaker Area Development Corporation, Neighborhood Progress, Inc.
and the St. Luke's Foundation.
CDC Service Areas
The community development corporation (CDC) service areas are the geographic areas served by
the CDC. These areas are comprised of census blocks.
Cleveland Planning Districts
There are six planning districts in the City of Cleveland. These six districts are comprised of
groups of contiguous neighborhoods (spas). They do not follow the six police districts exactly.
Geographic reference maps
The Center has created geographic reference maps showing the cities, townships and
villages within each of the 17 counties included in NEO CANDO. Within Cuyahoga County we also have maps for each of the 36 statistical planning areas in the City
of Cleveland. The maps also include the census tracts that are within or cross
the neighborhoods, cities, townships or villages. To view these geographic
reference maps click
