Check out the outstanding independent reviews of GeoLytics products
"GeoLytics' CensusCDs Provide Data with Ease...
The company's CensusCDs are perhaps its best-selling product, providing census
data and basemaps from 1970 to 2000. The value that CensusCDs add over obtaining
census data directly from the U.S. Census Bureau is that they make finding data
faster and easier, and users can export the data in GIS-ready formats... products
are extremely easy to learn and use. I was extracting data and maps within two
minutes of installing the products. Also, they all work approximately the same:
you simply elect the region you're interested in, the type of geographical units
(for example, tracts and counties), the specific variables, the name for the
output file, and whether you want data only or data and a basemap. For the most
part, data extraction is rapid... [GeoLytics] products in combination not only
provide rapid access to all Summary File 3 data but also allow users to map
change over time with the unprecedented geographical precision of block groups
or tracts. To accomplish this, one must extract the same data from each database
(1990 and 2000), then join the 1990 and 2000 data tables to the basemap.
Fortunately, with the CensusCDs the process is straightforward because the
geographic area codes, such as tract numbers, are formatted identically in all
export files... [GeoLytics] Neighborhood Change Database is the only available
source that I know of that provides easy access to digital maps and data for the
1970 and 1980 census years... Moving from installation to operation took only a
few minutes. If you wish to look at change over time,
CensusCDs will be the only option available... So, if temporal analysis
or ease of learning is your primary objective, the CensusCDs are an excellent
"Through Geolytics' custom interface the user can access the 1990 data
either by one of the 12 geographic areas or by a radius around a specific
coordinate (latitude/longitude). The user can run specific requests and
return them in a variety of formats, such as all counts and summary reports
or dBase and ASCII formats, for use in statistics, spreadsheet, and database
packages... One can also create a thematic map of the various geographic
boundaries and data. The user can easily change themes, classification, labels,
and color schemes. A map can be printed or exported as a bitmap file for use
in word processing and graphics programs. It can also be exported as a shape
file or mid/mif for use in Geographic Information System (GIS) software...
The software is easy to use, with an intuitive interface and
good documentation. Furthermore, the consistency of the interface design
across Geolytics' software suite makes it easy for users to learn its new
products. The technical support is superb... The Bottom Line: If you or
your patrons need to compare 1990 to 2000 census data for a broad area in a
timely manner, then CensusCD 1990 Long Form in 2000 Boundaries is your product.
There is currently nothing on the market that competes.
Accessing, normalizing, and comparing census data from multiple time periods
has been an arduous task, but this product makes it easy. Recommended
for mapping collections."
"GeoLytics serves up the U.S. 2000 Census data in a user-friendly interface.
CensusCD 2000 Long Form offers detailed information about population,
housing, and economics from the U.S. Census Bureau's SF3 data file... The 2000
Long Form offers more than 400 variables, such as educational attainment,
language spoken, ancestry, and housing information. These can be cross-tabulated
(e.g., income by age, employment by race), resulting in about 16,000 variables
at the tract level and above and about 5500 variables at the Block Group level...
CensusCD 2000 Long Form has data at 12 levels of geography from the
entire nation down to urban designations, American Indian Reservations down to
Block Groups... Searching and producing reports or maps is handled niftily by
GeoLytics's software, familiar to those who have used any of its products.
Neophytes will be able to follow directions easily and productively. Data may
also be exported into statistical or mapping packages. The web site offers a
clear and concise tour. The Bottom Line:... GeoLytics enables users to
build and execute queries across geographies that (the Census Bureau's)
FactFinder does not and to do so in a one-step operation.
For all libraries supporting research using detailed U.S.
demographics, your patrons will applaud you for making this product available.
"Users of digital census material covering 1980-2000 will be pleased to see
the release of CensusCD 1970, the first product to allow access to the complete
results of the 1970 U.S. census... GeoLytics had to create 1970 boundaries
for states, counties, and tracts, as these never existed in digitized form...
The main points are that 1970 data are easily searchable and quickly reportable
on this disc. The usual output options are available. The
Bottom Line: Another high-quality product from this reliable company,
CensusCD 1970 is highly recommended for public, academic, and special libraries
supporting research and planning via U.S. demographics."
"This product is incredibly easy to use, as illustrated by this extract from
the Short Form tutorial: "To create a report by state, this is what you do:
1. you click a state; 2. its counties are displayed, you click some; 3. you do
the same with tracts; 4. and Block Groups. Then you press Done and you are
Finished!" It doesn't get any simpler than this... Mapping and statistical
tools are built into this product, and exporting shape or MID/MIF (management
information format) files for more sophisticated Geographic Information Systems
(GIS) packages are also available. The key to this product is
its ease of use, with flexibility for extending analysis and presentation.
Help files (online and specifically for the map viewer) are included, along with
documentation provided by the Census Bureau... The Bottom Line: CensusCD
2000, Short Form is highly recommended for all institutions supporting
researchers needing information from the U.S. census, from high school civics
students to doctoral researchers to business and urban planners. An essential
"The breadth and depth of data presented makes [CensusCD 1990 Blocks] a
valuable tool, and the well-organized interface
allows even relatively inexperienced users to extract, present, and save
customized information. The fact that it is all contained in
one disc should be a sanity and self space saver for libraries needing a
flexible demographic/GIS tool to serve both novice and expert needs."
"CensusCD+Maps puts a wealth of demographic data at your fingertips...
In today's marketplace, businesses need easy-to-access, high-quality information.
For population, housing and economic information, CensusCD+Maps is hard to beat...
The big news in CensusCD+Maps is the '+Maps.' Instead of exporting tabular data
to a geographic information system or desktop mapping package, users can generate
thematic maps directly in the software...As though viewing and printing maps
wasn't enough, CensusCD+Maps supports map data export in both Arc View shapefile
and MapInfo MIF formats. The packaging of this product is
outstanding. Using nothing more than the two-page cover to the CD-ROM
package, the reviewer installed the software, defined a query and produced a
map... Strengths: Quantity of information, ease of use
and price. Weaknesses: None."
"A high-tech twist to the Census... Whatever the  census produces
will only make sense in context... That's where a new version of
CensusCD becomes indispensable. On merely one disk, the
old version of CensusCD carried a staggering amount of data: every total for
every 1990 census question for every neighborhood, city, county, state and
region... Now comes CensusCD+Maps, which carries all that data plus a simple
but slick mapping engine. It also includes 1997 estimates and projections to
2005 for 65 demographic categories such as age, race, income and employment
groups, along with housing status and types. The screen design is clear enough
that many people won't need to read the instructions to choose a category (like
median household income) and an area (like a county) and map it by smaller
areas, like neighborhoods."
"CensusCD is notable for two key characteristics: the sheer quantity of
data provided on the CD and the user-friendly interface used to quickly produce
data reports and tables. With the incorporation of mapping capabilities and
additional databases, CensusCD+Maps represents a major step forward in the query
and display of census data...Overall, I was surprised by the mapping
functionality of CensusCD+Maps. It approaches that of desktop GIS packages and
is even superior in some respects, such as its ability to quickly map a series
of variables in a scrolling list... The completeness,
capabilities, and convenience of CensusCD+Maps make it a vital resource
for those who regularly use census and related data."
"What makes the GeoLytics CD a quantum leap over census data on the
Internet is that it allows you to pull up demographic information on a
series of geographic areas -- a group of towns or neighborhoods, for
example -- and compare them. The raw data to do those kinds of investigations
was available before, but building a database or spreadsheet to work with it was
an arduous job. The GeoLytics CD makes it simple to export
information to a database or spreadsheet, and you don't have to deal with
overloaded servers and long download waits for telephone modems... I
particularly liked the Neighborhood Snapshot feature. By simply typing in your
ZIP code and street address, you can call up an instant and very useful,
demographic profile of your neighborhood. You can also customize the portrait to
include demographic information for an area within a designated number of miles."
