57254 Federal Register / Vol. 75, No. 181 / Monday, September 20, 2010 / Notices 

The re-engineering of SIPP pursues 

these objectives in the context of several 

goals—cost reduction and improved 

accuracy, relevance, timeliness, reduced 

burden on respondents, and 

accessibility. The Re-engineered SIPP 

will collect detailed information on cash 

and non-cash income (including 

participation in government transfer 

programs) one time per year. A major 

use of the SIPP has been to evaluate the 

use of and eligibility for government 

programs and to analyze the impacts of 

options for modifying them. 

A key component of the reengineering process involves the 

proposed shift from the every-fourmonth data collection schedule of 

traditional SIPP to an annual data 

collection schedule for the reengineered survey. To accomplish this 

shift with minimal impact on data 

quality, the Census Bureau proposes 

employing the use of an event history 

calendar (EHC) to gather SIPP data. The 

Re-engineered SIPP will interview 

respondents in one year intervals, 

collecting data for the previous calendar 

year as the reference period. The 

content of the Re-engineered SIPP will 

combine the content of the 2008 Panel 

SIPP core as well as selected topical 

module questions. The Re-engineered 

SIPP will not contain free-standing 

topical modules. The EHC will allow 

recording dates of events and spells of 

coverage and should provide monthly 

transitions of program receipt and 

coverage, labor force transitions, health 

insurance transitions, and others. 

As the SIPP transitions from three 

interviews per year to one interview per 

year, new methods need to be tested for 

how to stay in contact with respondents 

so they can be located for the following 

year’s interview. Once interviews have 

been completed for the 2011 SIPP field 

test, a recontact experiment will take 

place. The objectives of this experiment 

are: (1) To test how a combination of 

change of address cards mailed with or 

without a small monetary incentive, a 

newsletter reporting findings from the 

2008 SIPP Panel, or no contact between 

interview periods, effect attrition and 

the ability to locate respondents in the 

second wave of interviewing (Type A 

and Type D wave 2 non-response), and 

(2) to develop address update 

procedures which will facilitate locating 

original sample members who may have 

moved, and which can be implemented 

prior to and during the next interview 

field period. 

As part of the recontact experiment 

we will be mailing out a letter of 

explanation with the change of address 

cards. The SIPP–2011DR106(L) will be 

mailed to a subset of cases with the offer 

of monetary incentive. The SIPP– 

2011DR107(L) will be mailed to a subset 

of cases that will not offer a monetary 

incentive. 

Implementing the EHC methodology 

in 2011 is intended to help respondents 

recall information in a more natural 

‘‘autobiographical’’ manner by using life 

events as triggers to recall other 

economic events. For example, a 

residence change can in many cases 

occur contemporaneously with a change 

in employment. The entire process of 

compiling the calendar focuses, by its 

nature, on consistency and sequential 

order of events, and attempts to correct 

for otherwise missing data. For example, 

if the respondents are unemployed, they 

may then look for a job, and then 

become employed. 

The 2011 Field Test instrument will 

be evaluated in several domains 

including field implementation issues 

and data comparability vis-a`-vis the 

SIPP 2008 Panel and administrative 

records. Distributional characteristics 

such as the percent of persons receiving 

TANF, Food Stamps, Medicare, who are 

working, who are enrolled in school, or 

who have health insurance coverage 

reported in the EHC will be compared 

to the same distributions from the 2008 

SIPP Panel. The primary focus will be 

to demonstrate to data users that the 

new instrument yields data for lowincome programs that are of sufficient 

quality. The field test sample is focused 

in low income areas in order to increase 

the ‘‘hit rate’’ of households likely to 

participate in government programs. In 

general, there are two ways we will 

evaluate data quality: 

(1) We will compare monthly 

estimates from the field test to estimates 

from parallel sample areas in the 2008 

SIPP panel for characteristics such as 

participation in Food Stamps, TANF, 

SSI, WIC, and Medicaid. To the extent 

those estimates are reasonably aligned 

with each other, we can assume that 

data quality is reasonably comparable. 

Misalignment of the estimates, and 

especially misalignment in the direction 

of the EHC estimates being consistently 

lower than the SIPP estimates, would be 

worrisome, because it would be 

suggestive of (not definitive evidence of) 

reduced data quality in the EHC. 

(2) For a small subset of 

characteristics, and for a subset of 

sample areas, we will have access to 

administrative record data. These data 

will permit a more objective data quality 

assessment. 

Results from both the 2011 Field Test 

and the 2008 SIPP Panel will be used to 

inform final decisions regarding the 

design, content, and implementation of 

the Re-engineered SIPP for production 

beginning in 2013.

American Community Survey 5-Year 

Data Product Plans 

AGENCY: Bureau of the Census, 

Department of Commerce. 

ACTION: Final Notice. 

SUMMARY: The Bureau of the Census 

(Census Bureau) currently releases 

American Community Survey (ACS) 

data products in the form of 1-year 

estimates and 3-year estimates. Most 

recently, the 2008 ACS 1-year estimates 

were released in September 2009, and 

the 2006–2008 ACS 3-year estimates 

were released in October 2009. By this 

notice, the Census Bureau announces 

plans for the release of ACS 5-year data 

products covering the period of 2005– 

2009. The release of the ACS 5-year 

estimates will achieve a goal of the ACS 

to provide small-area data similar to the 

data published after Census 2000, based 

on the long-form sample. This notice 

provides general information on the 

Census Bureau’s modifications to its 

current line of ACS data products to 

accommodate the 5-year estimates.

SUPPLEMENTARY INFORMATION: 

I. Purpose of the ACS 5-year Data 

Products 

The ACS is part of the 2010 Decennial 

Census Program and provides annually 

updated, detailed demographic, 

socioeconomic, and housing 

information for communities across the 

United States and Puerto Rico. One goal 

of the ACS is to provide small-area data 

similar to the data published after 

Census 2000, based on the long-form 

sample data. This goal will be met with 

the release of the 2005–2009 ACS 5-year 

estimates. 

On March 6, 2009, the Census Bureau 

published a Federal Register notice (74 

FR 9785) that proposed releasing the 5- 

year estimates using the same set of ACS 

data products that were produced for 

the ACS 3-year data estimates, and 

included proposed geographic summary 

levels for the 5-year data products. 

Descriptions of the suite of ACS data 

products follow: 

Detailed tables include the most 

detailed ACS data and cross-tabulations 

of ACS variables. 

Download files provide the detailed 

table estimates in comma-delimited, 

ASCII-formatted files that are in the 

standard Census ‘‘Summary File’’ 

format. 

Data profiles provide separate fact 

sheets on social, economic, housing, 

and demographic characteristics. 

Narrative profiles provide clear, 

concise, textual descriptions of the data 

included in the data profiles. 

Subject tables include detailed ACS 

data, organized by subject such as 

employment, education, and income. 

Selected population profiles provide 

social, economic, and housing 

characteristics for a large number of 

groups based on race, Hispanic origin, 

country of birth, and ancestry. 

Geographic comparison tables allow 

the comparison of ACS data for a given 

time period across a variety of 

geographic areas. 

Thematic maps provide graphic 

displays of the data available from the 

geographic comparison tables, which 

compare ACS data for different areas in 

a given time period. 

Public Use Microdata Sample (PUMS) 

Files provide access to ACS microdata 

for data users to create summaries that 

are not available as ACS summary 

products. 

In the March 6, 2009 Federal Register 

notice, the Census Bureau sought input 

and feedback on the suite of data 

products for the ACS 5-year estimates 

and in particular, expressed interest in 

data users’ specific feedback on the 

following four dimensions: 

1. Block Group Level Geography—The 

Census Bureau proposed releasing block 

group data only as downloadable 

Summary Files through the American 

FactFinder Download Center. The 

American Factfinder is the electronic 

system for access and dissemination of 

Census Bureau data on the Internet. 

Tables can be accessed through the 

American Community Survey Data Sets 

page on American FactFinder or 

downloaded in file format from the 

American FactFinder Download Center. 

2. Types of Data Products—The 

Census Bureau proposed releasing 5- 

year estimates in detailed tables, 

summary files, subject tables, data 

profiles, narrative profiles, selected 

population profiles, thematic maps, 

geographic comparison tables, and 

PUMS files. Narrative profiles and 

selected population profiles were not 

proposed for particular geographic 

summary levels, such as block groups. 

3. Restrictions Required for Disclosure 

Avoidance or Statistical Reliability—As 

done with all data released by the 

Census Bureau, the proposal included 

restrictions on the release of 5-year 

estimates that were based on disclosure 

avoidance requirements. 

4. Frequency of Data Release—The 

Census Bureau proposed that ACS 5- 

year estimates be released annually. 

II. Summary of Comments Received 

and the Response of the Census Bureau 

The Census Bureau received 

comments from 26 organizations and 

individuals regarding the four abovementioned categories, in response to the 

March 6, 2009 Federal Register notice. 

Some commenters addressed more than 

one category in their comments. All 

comments have been summarized and 

organized according to subject matter. 

The subject matter categories are: (1) 

The option of alternative dissemination 

methods for data at the block group 

geography level, (2) the types of data 

products to be included in the 5-year 

data products, (3) the limitations on the 

availability of the 5-year estimates due 

to restrictions required for disclosure 

avoidance and statistical reliability, and 

(4) the proposed annual release for the 

ACS 5-year data products. Comments 

were provided by a variety of Federal 

and State agencies and organizations, 

non-profit policy research and analysis 

organizations, non-governmental 

organizations, and a private sector 

company. Federal, State, local, and 

private sector organizations from 

agencies representing the transportation 

community provided 17 of the total 26 

comments received. All comments 

received are posted on the Census 

Bureau’s ACS Web site, http:// 

www.census.gov/acs. A summary of the 

comments and the Census Bureau’s 

response is below. 

1. Block Group Level Geography 

The Census Bureau received six 

comments in response to the question of 

using downloadable Summary Files 

rather than releasing tables on American 

FactFinder for block group data. All six 

comments were in favor of ACS 

producing block group level data and 

releasing the block group data tables 

separately from the standard ACS tables 

currently found on American 

Factfinder. Two comments strongly 

recommended not releasing block group 

data tables on American Factfinder. 

Specifically they wanted the block 

group data released with cautions and 

instructions for combining data for 

block group areas into larger geographic 

areas ‘‘to achieve greater reliability.’’ 

In considering this proposal, the 

Census Bureau reviewed the complexity 

of using the block group data with the 

sheer volume of the estimates to be 

produced for approximately 210,000 

block group geographies and agreed that 

releasing tables on American Factfinder 

was not the preferred approach. As a 

result of public comments and staff 

review, the Census Bureau will release 

to the public through the American 

Factfinder Download Center the block 

group estimates only as files that can be 

accessed by more sophisticated users. 

2. Types of Data Products 

The Census Bureau received thirteen 

comments in response to the proposed 

data products for the ACS 5-year 

estimates. The comments were all in 

support of the data products proposed; 

one group interested in data on 

American Indian and Alaska Native 

(AIAN) populations requested specific 

AIAN data products. The Census Bureau 


jdjones on DSK8KYBLC1PROD with NOTICES
57256 Federal Register / Vol. 75, No. 181 / Monday, September 20, 2010 / Notices 

agrees with the comment and plans to 

produce data specifically for American 

Indians and Alaska Natives with the 

release of the 2006–2010 ACS American 

Indian and Alaska Native Summary 

File. One comment from the 

transportation community requested 

expanded transportation data, and six 

comments were concerned about how 

confidentiality protections might limit 

the availability of detailed 

transportation data at very low levels of 

geography. These confidentiality 

protections focus on tables that have 

many cells but few sample cases. To 

address the concerns expressed in the 

comments, the Census Bureau has for 

several years been working with the 

transportation community to develop 

ACS data products that provide a 

balance between the low geographic 

levels required by the work of the 

transportation community and 

confidentiality protections required by 

the Census Bureau’s collection 

authority, Title 13. For example, the 

ACS 1-, 3- and 5-year standard data 

products now contain 59 new 

transportation tables that were not a part 

of the Census 2000 standard data 

products; some of these ACS 

transportation tables had formerly only 

been provided through custom 

tabulation requests paid for by the 

transportation community (in Census 

2000 and earlier censuses). The Census 

Bureau is also providing some tables 

with low geographic levels of 

transportation data sooner and more 

frequently in the ACS data products 

than they have from past Censuses. 

Finally, the Census Bureau continues to 

work in collaboration with the 

transportation community to determine 

the best set of products to provide more 

data for very small geographic areas 

without violating confidentiality 

protections. One comment from a 

private sector firm offered suggestions 

for organizing ACS data for download to 

enhance analysis. The Census Bureau 

agrees with this comment and is 

developing improvements for data 

products available for download. 

To arrive at a final plan for the data 

products to be released for the 2005– 

2009 ACS, the Census Bureau 

considered all comments and also 

undertook a comprehensive staff review 

of the many ACS data products released 

for the 3-year estimates. The objective of 

this review was to determine if those 

products were appropriate for very 

small counties, towns, and incorporated 

places, as well as for specific 

government data uses and public use. 

The final plan for the ACS 5-year data 

products will provide a very large 

percentage of the data that were 

previously found in Census Summary 

Files 1 and 3. Some tables previously 

provided only upon request for a 

custom tabulation will be made 

available routinely to the public in the 

standard ACS data products. 

Additionally, tables not present in 

Census 2000 data products have been 

added to this set of available ACS tables. 

When comparing the plan for the 2005– 

2009 ACS to what was released in 

Census 2000, most of the new tables 

reflect new content, but some tables 

were added because they were 

determined by subject matter experts to 

be desirable by data users. 

Census Bureau staff also reviewed the 

practical matter of providing public 

access to the large volume of data being 

produced by releasing 5-year estimates 

for such a large number of geographic 

areas. Staff reviewed the available data 

products and tables and determined that 

a reduced set of tables will be released 

on American FactFinder with the 

remainder to be available to the public 

through downloadable Summary Files 

from the American FactFinder 

Download Center. 

The Census Bureau plans to deliver to 

the public the tables for the 5-year 

estimates on American FactFinder in a 

single release. The release of the 

Summary Files (including all data at the 

block group level) and the PUMS files 

will follow soon after the initial release 

of tables on American FactFinder. The 

plan for future releases of the ACS 5- 

year data products may be subject to 

change as Census Bureau staff improves 

the data products and receives input 

and feedback from data users. 

3. Restrictions Required for Disclosure 

Avoidance or Statistical Reliability 

The March 6, 2009 Federal Register 

notice directed readers to a file 

containing supplementary information 

located on the Census Bureau’s Web site 

(http://www.census.gov/acs). The table 

describing disclosure avoidance 

protections was in the file that provided 

this supplementary information, and 

these protections were listed by number. 

The Census Bureau received 20 

comments in response to the proposed 

disclosure avoidance. Three comments 

supported the Census Bureau’s plans for 

disclosure avoidance. Some 

commenters, mostly from the 

transportation data community, had 

comments or suggestions concerning 

disclosure avoidance. Disclosure 

avoidance number seven from the 

March 6, 2009 Federal Register notice 

stated 

For the residence and workplace tables 

where means of transportation (mode) is 

crossed with one or more other variables, 

there must be at least three unweighted 

workers in sample for each transportation 

mode in a given place for the table to be 

released. Otherwise the data must be 

collapsed or suppressed and complementary 

suppression must be applied. There is no 

threshold on univariate tables. 

Commenters expressed objections to 

disclosure avoidance number seven, 

stating that its implementation would 

negatively impact data needed for 

planning requirements, particularly for 

very small geographic levels including 

traffic analysis zones and block-groups. 

In response to these concerns, Census 

Bureau staff reviewed the published 

disclosure avoidance and determined 

that number seven, which impacts 

residence and workplace tables where 

means of transportation (mode) is 

crossed with one or more other 

variables, does not apply to the standard 

ACS data products, but rather it applies 

only to some custom tabulations that the 

Census Bureau produces upon request. 

However, because of general Census 

Bureau Disclosure Review Board 

restrictions pertaining to non-residential 

geographies, some of the tables of 

interest to transportation data users will 

still be limited or suppressed. The 

Census Bureau is aware of the needs 

that the transportation community has 

for these data and has expanded the 

number of transportation tables in the 

ACS standard annual data products to 

include ones that were not provided in 

Census 2000 standard tabulations. In 

addition, the Census Bureau continues 

to work closely with staff from the 

Department of Transportation to 

produce custom tabulations that will fit 

the needs of transportation data users 

and that also uphold the Census 

Bureau’s duty to protect the 

confidentiality of ACS respondents. 

Additionally, another commenter was 

concerned that disclosure avoidance 

number six would suppress data for 

small reservations and many Alaska 

Native Village Statistical Areas. 

Disclosure avoidance number six from 

the March 6, 2009 Federal Register 

notice stated: 

For workplace tables, there must be at least 

50 unweighted or 300 weighted workers in 

sample over the 5-year period in a given 

workplace for the table to be released. 

Census Bureau staff recognizes the 

difficult balance in producing tables for 

small populations and ensuring that 

confidentiality is protected. Disclosure 

avoidance number six, originally 

developed for Census 2000 data, had a 

restriction of workplace tables to areas 

with 50 unweighted or 300 weighted 

workers. The 300 weighted workers 

restriction was based on the 50

Federal Register / Vol. 75, No. 181 / Monday, September 20, 2010 / Notices 57257 

1Because the vote of the ITC with respect to 

imports of MCB from Mexico was evenly divided 

between an affirmative determination of material 

injury and a negative determination, the 

Department is treating this vote, for purposes of 

duty assessment, as an affirmative finding of 

material injury consistent with section 771(11) of 

the Act. Likewise, because the vote of the ITC with 

respect to imports of MCB from the PRC was evenly 

divided between a determination of material injury 

and a determination of threat of material injury, the 

Department is treating this vote, for purposes of 

duty assessment, as an affirmative finding of 

material injury consistent with section 771(11) of 

the Act. 

2Critical circumstances were not alleged with 

respect to imports of subject merchandise from 

Mexico. 

unweighted workers and the Census 

2000 average long form weight of six. 

The Disclosure Review Board, upon 

closer review for the ACS 5-year data 

products, decided that the key 

restriction to protect confidentiality for 

the ACS was the 50 unweighted 

workers, so the reference to a weighted 

number of workers has been dropped. 

Census Bureau staff also expanded the 

language on disclosure avoidance 

number six to clarify that in addition to 

workplace tables, the requirement for at 

least 50 unweighted workers in sample 

over the 5-year period applies to all 

non-residential geographies including 

residence 1 year ago and place-of-birth 

tables. 

4. Frequency of Data Release 

The Census Bureau received five 

comments on the proposed annual 

release of the ACS 5-year estimates. All 

five comments were in favor of the 

annual release. 

III. ACS 5-year Data Products Plans 

The Census Bureau is releasing its 

plans for the ACS 5-year data products 

via the Web. The plan provides a list of 

the tables and geographies expected to 

be included in the ACS 5-year products 

and will be updated periodically with 

new and expanded information. This 

information can be accessed at: http://

ITC notified the Department of its 

affirmative determinations of material 

injury to a U.S. industry. See Certain 

Magnesia Carbon Bricks from China and

SUPPLEMENTARY INFORMATION: 

Background 

On August 2, 2010, the Department 

published its affirmative final 

determinations of sales at less than fair 

value in the antidumping duty 

investigations of MCB from Mexico and 

the PRC. See Certain Magnesia Carbon 

Bricks from Mexico: Notice of Final 

Determination of Sales at Less Than 

Fair Value, 75 FR 45097 (August 2, 

2010); and Certain Magnesia Carbon 

Bricks from the People’s Republic of 

China: Final Determination of Sales at 

Less Than Fair Value and Critical 

Circumstances, 75 FR 45468 (August 2, 

2010) (MCB from the PRC Final). 

On September 8, 2010, the ITC 

notified the Department of its final 

determinations pursuant to section 

735(d) of the Tariff Act of 1930, as 

amended (the Act), that an industry in 

the United States is materially injured 

by reason of less-than-fair-value imports 

of MCB from Mexico and the PRC.1See 

section 735(b)(1)(A)(i) of the Act. In 

addition, the ITC notified the 

Department of its final determination 

that critical circumstances do not exist 

with respect to imports of subject 

merchandise from the PRC that are 

subject to the Department’s affirmative 

critical circumstances finding.2

Pursuant to section 736(a) of the Act, 

the Department is publishing 

antidumping duty orders on the subject 

merchandise. 

Scope of the Orders 

The scope of these orders includes 

certain chemically-bonded (resin or 

pitch), magnesia carbon bricks with a
