"Update block," for which staff are assigned specified blocks to canvass in order to find and record addresses not in the MAF, correct and unduplicate information for the addresses recorded in the MAF, record or correct the approximate location of each address, and update and correct street/road information.

"Locate address," for which staff are assigned specific addresses recorded in the MAF. Using the ALMI, they can display a map for a specific block, nearby blocks, and, if necessary, an overview or "locator" map of a county, census tract, governmental unit, etc., in an effort to try to find each address on the ground.

They also could identify 1) features Block Boundary BBSP they did not want held as block boundaries; 2) features they Suggestion Project wanted held as block boundaries on a contingency basis, such as the imaginary extension of a street to a city limit if that

See assignment area map, block locator map, block number, collection block, and map spot.

A number assigned to each census block.

For collecting information for Census 2000, each census block was identified uniquely within a county-(or statistically equivalent entity) by a 4- or 5-digit number. All the collection blocks in a county used the same number of digits.

As a result of changes to the TIGER database 'after the Census Bureau had numbered the blocks in preparation for the Census 2000 field operations, the number could have an alphabetic suffix, to represent one portion of a physical block that was split by an added street or road or by the addition or change of the boundary of a county, American Indian reservation, off-reservation trust land, or military installation; block number for example, if an added street bisected Block 1005, the*

'block was split into Blocks 1005A and 1005B to represent

. the portion of the orignal collection block on each side of that _7:7 street.

For tabulating data for Census 2000, each census block was

. _ -identified uniquely within a census tract by a 4-digit number.

A 1990 census block number had three digits; with a potential alphabetic suffix. The first digit identifies the block group in which the census block is located. _

The establishment, relocation, or deletion of a boundary.

source. For statistical entities, boundary changes are provided boundary change -in preparation for a specific census in response to the Census

--Burea9's Pirtiiphai Statistical Areas Program or some other specific boundary collection program. The boundaries of legal entities are changed due to legal actions, whereas statistical entities may be changed by appropriate reviewers to reflect population growth or decline, or because of revisions either to visible or legal features used as boundaries or to Census Bureau procedures. A boundary change also can occur due to an error in recording a boundary for one census or survey, and showing it correctly for the next.

' Questionnaires checked in at the four data capture centers represented the initial step for processing responses to Census 2000. Check-in at the data capture centers was an operation designed to record receipt of census questionnaires into a database for control and workflow management. It provided an estimate of the scanning workload. The check-in count of questionnaires included all mailed-in questionnaires, including responses from mailout/mailback, update/leave, and the Be Counted Program, and enumerator interview check-in rate

- responses, including list/enumerate, update/enumerate, and Nonresponse Followup. The check-in count also included questionnaires returned as undeliverable-as-addressed by the U.S. Postal Service. Some questionnaires included in check-in may be duplicate forms from the same household, blank forms, and the like; because questionnaires from all of these sources constitute the questionnaire scanning workload, the Census Bureau does not reduce the check-in count by the number of unusable questionnaires.

As a result, each tribe or base worked with only one LCO for the census.

--- block in the United States and Pureto Rico. The 3-digit ZCTAs for the dress rehearsal used two blank spaces instead of suffixes. ZCTAs do not include all ZIP Codes used for mail delivery. The Bureau first created ZCTAs for the
