Although there are many aspects of Census 2000 that are different from the 1990 Census, the key differences were Created a new "user-friendly" questionnaire that was simpler and easier for respondents to understand and fill out. Digitally captured of forms enabling us to scan responses directly into computers that can read handwriting. Used "matching" software that allows us to check individual blocks and identify multiple responses from the same household.

Only one new subject was added to the Census 2000 questionnaire: grandparents as caregivers. This addition complies with legislation passed by the 104th Congress requiring that the decennial census obtain information about grandparents who have primary responsibility for care of grandchildren (Title 13, United States Code, Chapter 5, Section 141).

Even though the codes may appear the same, the addresses and areas covered by these areas may not be the same. We strongly advise data users who wish to compare 1990 and 2000 data to determine and evaluate any coverage differences that exist before making any comparisons. There are several reasons for this caution: The USPS has extensively modified ZIP Codes over the last ten years.

For Census 2000, the Census Bureau has proposed subjects on the short form only when data are both needed in response to legislative requirements and required at the block level - the smallest level of geography for which we report information. Therefore, we moved five subjects that were asked of every housing unit in 1990 to the long form, which went out to a sample of housing units in 2000.

The U.S. Census Bureau provides Block Relationship files to help users determine how Census 2000 block data relates to data from 1990.

The data on race in Census 2000 are not directly comparable to data collected in previous censuses. For more information on race and Hispanic origin data, click on one of the following:

Deciding which subjects to include was an interactive process involving the Census Bureau, the Office of Management and Budget, and the U.S. Congress. To balance concerns about the intrusiveness of the decennial census, the many requirements placed on federal agencies, and the needs of state, local, and tribal governments to manage programs, only those subjects that had specific federal legislative justification were recommended for Census 2000.

Census 2000 data will be disseminated mainly using a new data retrieval system called the American FactFinder (AFF). Census 2000 data products will be available on a flow basis beginning January 2001. The American FactFinder will be accessible to the widest possible array of users through the Internet, through intermediaries, including the nearly 1,800 State Data Centers and affiliates, the 1,400 Federal Depository libraries and other libraries, universities, and private organizations.

The Census 2000 Partnership and Marketing Program was a multi-faceted effort to remind the general population about the census, educate those members of the public who do not understand the purpose of the census and its significance to their communities, and motivate them to complete their census questionnaires. The Census Bureau recognizes that different segments of the population respond in different ways and with different levels of trust and willingness to participate in the census.

We will begin delivery of these data in March 2001 and we will complete delivery to the governor and majority and minority legislative leaders in each state by April 1, 2001. We will do all that is possible to consider each state’s redistricting deadlines as we plan the sequence of our data processing. Already we have confirmed with each state legislature any deadlines the state faces.

For Census 2000 the Census Bureau included overseas counts in the census using definitions and procedures similar to those used in 1990. U. S. military and federal civilian personnel stationed overseas and their dependents living with them were included in the overseas population counts and the Census 2000 apportionment counts. Included in these counts were members of the U.S. Armed Forces on military vessels assigned to a home port in a foreign country and their dependents overseas with them.

The major features of automation for Census 2000 include data capture methodology that accommodated the use of respondent-friendly questionnaires. The Census Bureau has identified components of the data capture process that may be best performed by private-sector partners although it did not limit itself to creating in-house solutions. The Census Bureau took advantage of available commercial off-the-shelf hardware and software representing advancements in information technology and systems.

The address list and related maps are the foundation of a complete and accurate census. Some of the people not counted in the 1990 census were missed because the Census Bureau did not know their housing units existed. A complete address list will ensure that Census 2000 will be accurate. Up-to-date maps helped the Census Bureau verify where each housing unit was located.

ZCTAs for the entire United States and Puerto Rico will be available in the Census 2000 TIGER/Line® files. ZCTAs are stored in Record Type S, which stores codes that relate to TIGER polygons. Generalized boundary files, including ZCTAs, that are appropriate for small-scale thematic mapping. These files are available for downloading from the Census Bureau's Cartographic Boundary Files site in the following formats: ARC/INFO Export (.e00), Arcview Shape (.shp), and ASCII.

Census 2000 is already under way, though not without controversy. After a lengthy disagreement on how to count urban areas that have traditionally been under-counted, Congress has allocated funds for the decennial census enumeration.

In 1920, the census asked "if naturalized, year of naturalization." In 1930, the Census asked only if the person were naturalized. The 1900, 1910, and 1920 censuses asked if a person owned or rented a house. In 1930, the schedules also included the value of the home or the amount of rent paid each month.

The Web page for the 1990 Census of Population and Housing is: http://www.census.gov/main/www/cen1990.html. Two data sets from this census are available in American FactFinder on the Data Sets page. The Web page that explains where to locate historical census data held by the Census Bureau is: http://www.census.gov/population/www/censusdata/hiscendata.html. This is where you would begin the search for any data related to any decennial census prior to 1990.

The TIGER/Line files that should be used with the 2000 Census data are those in the TIGER/Line 2000 release. These files are available for downloading for free from the Census Bureau’s website. Go to the TIGER page http://www.census.gov/geo/www/tiger/ for links to the files and the documentation.

There are several options for determining the census 2000 tract, block group or block number for a given area. The most convenient method for determining census tracts and block groups for those with Internet access is to visit the Census Bureau’s American FactFinder website http://factfinder.census.gov/. There one can view a map of the area of interest and select the types of boundaries to be shown, including tract and block group.

The following are U2's studio albums and officially released live compilations, with the producer and the date of release in brackets. The following is a list of U2's commercially released singles. The intent is to provide general information, not to cover every variation of every single in each country that it was released. This list includes appearances by the entire band.

The three models that make up the CE Series all provide legendary Crown performance in a very affordable package. All models are similar in their features and appearance. Balanced Current Amplifier (BCA) output circuitry and switching power supply for more power and less heat and weight than traditional linear amplifiers. Power Factor Correction (PFC) for global power compatibility, which means the CE 4000 will work with any common line voltage and frequency.

Answer: Data on race from Census 2000 are not directly comparable with those from the 1990 census and previous censuses due, in large part, to giving respondents the option to report more than one race. Other factors, such as reversing the order of the questions on race and Hispanic origin and changing question wording and format, also may affect comparability.

Differences between 1990 Census data products may reflect differences in sampling and estimation techniques applied to different questionnaires administered nationwide. The numeric information provided here has been extracted, and in some cases aggregated, from tables in one U.S. Bureau of the Census data product: Census of Population and Housing, 1990: Summary Tape File 3A on CD-ROM (Pennsylvania: Philadelphia-York) [machine-readable data files] / prepared by the Bureau of the Census.
