Constitutionality of Excluding Aliens from the Census: Apportionment and Redistricting

Constitutionality of Excluding Aliens from the Census: Apportionment and Redistricting
By: Margaret Mikyung Lee and Erika K. Lunder
Source: Congressional Research Service

From the Summary:
In the 2010 decennial census, the Census Bureau will attempt to count the total population of the United States. This includes, as in previous censuses, all U.S. citizens, lawfully present aliens, and unauthorized aliens. Some have suggested excluding aliens, particularly those who are in the country unlawfully, from the census count, in part so that they would not be included in the data used to apportion House seats among the states and determine voting districts within them.

One question raised by this idea is whether the exclusion of aliens could be done by amending the federal census statutes, or whether such action would require an amendment to the Constitution. The Constitution requires a decennial census to determine the “actual enumeration” of the “whole number of persons” in the United States. The data must be used to apportion the House seats among the states, although there is no constitutional requirement it be used to determine intrastate districts. It appears the term “whole number of persons” is broad enough to include all individuals, regardless of citizenship status, and thus would appear to require the entire
population be included in the apportionment calculation. As such, it appears a constitutional amendment would be necessary to exclude any individuals from the census count for the purpose of apportioning House seats.

The Census Bureau will release a set of four national projections supplementing the series released in August 2008, showing projections to 2050 by age, race, sex and Hispanic origin. These four scenarios assume either high, low, constant or zero international migration between 2000 and 2050. The August 2008 projections remain the preferred series for users.

Musings on privacy issues in health research involving disaggregate geographic data about individuals

Musings on privacy issues in health research involving disaggregate geographic data about individuals (Editorial)
By: Maged N Kamel Boulos, Andrew J Curtis, and Philip AbdelMalik
Source: International Journal of Health Geographics

This paper offers a state-of-the-art overview of the intertwined privacy, confidentiality, and security issues that are commonly encountered in health research involving disaggregate geographic data about individuals. Key definitions are provided, along with some examples of actual and potential security and confidentiality breaches and related incidents that captured mainstream media and public interest in recent months and years. The paper then goes on to present a brief survey of the research literature on location privacy/confidentiality concerns and on privacy-preserving solutions in conventional health research and beyond, touching on the emerging privacy issues associated with online consumer geoinformatics and location-based services. The ‘missing ring’ (in many treatments of the topic) of data security is also discussed. Personal information and privacy legislations in two countries, Canada and the UK, are covered, as well as some examples of recent research projects and events about the subject. Select highlights from a June 2009 URISA (Urban and Regional Information Systems Association) workshop entitled ‘Protecting Privacy and Confidentiality of Geographic Data in Health Research’ are then presented. The paper concludes by briefly charting the complexity of the domain and the many challenges associated with it, and proposing a novel, ‘one stop shop’ case-based reasoning framework to streamline the provision of clear and individualised guidance for the design and approval of new research projects (involving geographical identifiers about individuals), including crisp recommendations on which specific privacy-preserving solutions and approaches would be suitable in each case.

The Stat Police

A story from NPR's On the Media:

Politicians and journalists frequently cite statistics that are misleading, derived from dubious studies, or simply plucked out of thin air. So the U.K. has done something novel: they’ve created a new government agency to ensure that those all-important stats aren't fudged for political purposes. Chairman of the U.K. Statistics Authority, Sir Michael Scholar, explains what they do.

CDC Releases New Infant Mortality Data

CDC Releases New Infant Mortality Data

The United States ranked 29th in the world in infant mortality in 2004, compared to 27th in 2000, 23rd in 1990 and 12th in 1960, according to a new report from CDC?s National Center for Health Statistics. The U.S. infant mortality rate was 6.78 infant deaths per 1,000 live births in 2004, the latest year that data are available for all countries. Infant mortality rates were generally lowest (below 3.5 per 1,000) in selected Scandinavian (Sweden, Norway, Finland) and East Asian (Japan, Hong Kong, Singapore) countries. Twenty-two countries had infant mortality rates below 5.0 in 2004.

Births, Marriages, Divorces, and Deaths: Provisional Data for 2007

Births, Marriages, Divorces, and Deaths: Provisional Data for 2007
Source: National Center for Health Statistics (CDC)

Data shown here are provisional and include only events occurring within the United States (50 states and the District of Columbia). Provisional birth, death, and infant death data in this report are based on a combination of counts of events provided by each reporting area and registered vital events processed into National Center for Health Statistics (NCHS) data files. Some of these may not have occurred in the specified month of this report. Monthly provisional birth, death, and infant death data may be updated during the course of a data year. Updates based on registered events will be included in the month the event occurred. However, updates based on counts received from the states may include the event in the month it was processed rather than the month in which it occurred. This may result in a low figure for a given month followed by a high figure for the month(s) in which the delayed records were processed. Once the provisional data year has ended, updates cease. Thus, provisional birth, death, and infant death data may not accurately track either the preliminary or the final number of events registered.

American Time Use Survey (ATUS) in jeopardy

The President's proposed FY 2009 budget eliminates funding for the American Time Use Survey (ATUS) at the Bureau of Labor Statistics (BLS). Eliminating the ATUS would result in the loss of informative data on the full range of non-market activities Americans conduct. BLS needs $6.0 million in the FY 2009 budget to fully fund the ATUS and its other key surveys.

Census Won't Count Gay Marriages

Census Won't Count Gay Marriages
Christopher Lee | Washington Post

Although gay marriage is legal in Massachusetts and California, census officials say that same-sex partners in both states who list themselves as spouses will be recorded as "unmarried partners" -- just as they were in the 2000 census.

Census Bureau spokesman Stephen Buckner cited the Defense of Marriage Act, approved by Congress and signed by President Bill Clinton in 1996, which prohibits the federal government from recognizing as a marriage the union of anyone but a man and a woman.

NIH and Sensitive Data

NIH Reconfirms Commitment to Protecting Sensitive Personal Data

April 14, 2008

As a result of the recent theft of an NIH employee’s laptop which included storage of patient data, the NIH has refocused its efforts to protecting information systems (electronic and hard copy) which contain sensitive personal information. Steps are currently underway at NIH to ensure that all computers, laptops and portable electronic devices are encrypted and that NIH employees are educated in the proper handling of sensitive data.

In addition, the NIH encourages grantee institutions and individuals not to use portable electronic devices to store identifiable, sensitive, and confidential information about NIH-supported research or research participants. If they must be used, they should be encrypted to safeguard data and information. These devices include laptops, CDs, disc drives, flash drives, etc. Researchers and institutions should limit access to personally identifiable information through a means of access controls such as password protection.

For more information, see NIH Guide Notice, dated 4/11/2008.

UN Data Launched

UN data was launched in February 2008. It will replace the UN Commons database, which will be discontinued as of July 31, 2008.


UNdata is the United Nations Data Access System which gives access to current, relevant and reliable statistics for free. The service is provided by the United Nations to users of data around the world. It offers easy access to data compiled and produced by United Nations agencies as well as other organizations.

UNdata's main features are:
- accessing different data sources through one interface,
- searching data with keywords and browsing databases,
- refining search results by filtering, and
- customizing tables with features such as sorting, column
selection and pivoting.

UNdata and the UN Common Database (UNCDB) UNdata is replacing the UNCDB. The new system goes beyond the concept of the UNCDB, starting from the way the data is stored and searched to the data presentation. Furthermore, the UNCDB only includes a small selection of UNSD's extensive data collection, whereas UNdata will have broader data coverage from various international and national sources.

The UNCDB series are currently available through UNdata under the new name "Key indicators". Please note that the Key indicator's scope has already been reduced, as some of the series have been included from the original data provider.

The UNCDB will be discontinued this summer after the academic year finished in most schools around the globe.
