FAQs about Hispanics and Immigrants from the American Community Survey

The Pew Hispanic Center has updated its statistical profile of U.S. Hispanics, using data from the 2009 American Community Survey. The profile includes 40 tables on a variety of topics from living arrangements to income to citizenship. Also updated, using the 2009 American Community Survey, was the center’s profile of the U.S. foreign-born population, also consisting of 40 tables with details on characteristics of this population.

These updated profiles complement previously published state and county data for Hispanics from the 2008 American Community Survey.


India Census Offers Three Gender Options

India’s 2011 national census, which goes into the field this week, includes not just the usual two gender categories, but for the first time a third one, called “other.”  The national census in Nepal, to be conducted in May, also will include three gender options, prompted by a ruling by that nation’s highest court ordering greater protections for the rights of transgender, gay and lesbian and bisexual people.

As this posting from the Population Reference Bureau explains,  the “third sex” is not a recent concept in many parts of the world, although the change on the census form has generated many stories in the Indian press.

The U.S. census form, as shown here, offers the standard two options, male and female.


First Detailed Race Data for States from 2010 Census

The Census Bureau began a gigantic release of 2010 Census data today, publishing detailed race, Hispanic and population totals down to the block level for Louisiana, Mississippi, New Jersey and Virginia. The bureau will release data for the remaining states (and District of Columbia) over the next two months, with the final state numbers due out before April 1.

The legal purpose of this data is that it will be used as the basis for redrawing the boundaries of political districts within states, from congressional districts to local government boards. But the numbers also will have a fascinating story to tell about racial change, dispersion of the Hispanic population nationwide, population growth or decline and other themes.

A few of the earliest news stories include: Hispanics largest minority in New Jersey in the Star-Ledger; Asian and Hispanic populations skyrocket in Virginia in The Washington Post; New Orleans population drops since 2000 in the Times-Picayune; and Mississippi coast population loss not as great as feared in the Biloxi Sun Herald.


State Population Estimates and Census 2010 Counts: Did They Match?

How well did the Census Bureau’s population estimates for the first decade of the 21st century match the actual counts from the 2010 Census?  The short answer: Pretty well for the nation, and for all but a handful of states.

The accuracy of these population estimates is important because the numbers, which are released each year in between the once-a-decade census counts, are the basis for distributing billions of dollars in federal funds and are the denominators for rates used in some federal surveys. Unlike the census, which counts people directly, the estimates are assembled using government data, including birth and death certificates, immigration estimates and tax-return statistics on people who changed residences.

As Census Bureau Director Robert M. Groves pointed out in a news conference today, it greatly increases confidence in the census count if population numbers that are derived using different methods are similar. Groves said it reflects well on 2010 Census accuracy that the 2010 Census count for the nation, 308,745,538, was close to the bureau’s national population estimate of 308,977,944 on Census Day (April 1, 2010). The 2010 national count also matched up well with population estimates the bureau released last month using demographic analysis, an alternative measurement technique that uses a method somewhat similar to that used in the population estimates.

Digging into the estimates data, Pew Research Center demographer Jeffrey Passel has analyzed how the bureau’s population estimates for states compare with the official 2010 Census counts for states. He began with state estimates for July 1, 2009 (the latest available), and projected them forward to Census Day based on average growth rates for each state for 2007-2008 and 2008-2009. (This method produces a slightly different total for the nation than the Census Bureau computed, 309,081,328.) Read more


Census 2010: The Last Seat in Congress

A decade ago, the apportionment counts from the 2000 Census showed that North Carolina was the luckiest state in the country. Based on its population gains, it won the last seat in Congress, the 435th. In 2010, though, North Carolina’s fortunes were not as good.

When the 2010 Census apportionment counts were announced last month, they showed that North Carolina fell short of winning the 435th or last seat. This time, the 435th went to Minnesota. (If it is any comfort to North Carolinians, the state would have gained the theoretical 436th seat in Congress, if one existed.)

Census numbers are used to apportion seats in the U.S. House of Representatives using a formula that assigns each state one seat, and, one at a time, allocates the remaining 385 places. The allocation is based on the size of each state’s resident population, plus any overseas military and civilian federal workers (and dependents) from that state.

In 2010, North Carolina fell nearly 15,800 people short of the number it would have needed to win the last seat instead of having it go to Minnesota, according to calculations by Pew Research Center senior demographer Jeffrey Passel. Read more


Report: Hispanics Played Key Role in Census 2010 Growth

When the Census Bureau announced the first population totals from the 2010 Census for the nation (308.7 million) and for states on Dec. 21, the numbers did not include ethnic or race breakdowns. Those will be released later this year. A new report from the Pew Hispanic Center, using other Census Bureau data, concludes that Latinos played a key role in growth of the nation’s population and growth in states that gained congressional seats because of reapportionment, which is based on census numbers.

Using 2009 population estimates from the American Community Survey, Hispanics accounted for 51% of the nation’s population growth since the 2000 Census, which counted 281 million U.S. residents. From 2000 to 2010, the nation’s population grew 9.7%. From 2000 to 2009 (the last year available), the Hispanic population grew 37%.

Looking at population change for each state and the District of Columbia, Hispanics represent a greater share of eligible voter and resident populations in states that will gain congressional seats than in those states that will lose congressional seats, the report concludes. Hispanics represent 15.2% of eligible voters in the eight states that gained congressional seats, compared with 5.4% of eligible voters in the 10 states that lost congressional seats, according to estimates based on the 2009 American Community Survey. (Eligible voters are defined as U.S. citizens who are 18 years or older.) Latinos also represent 23.6% of the resident populations in states that gained seats, compared with 8.4% in states that lost seats.

The report makes the point that because many Latinos are either too young to vote or are not U.S. citizens, their population growth has not translated fully into electoral strength. However, the report states, “the electoral strength of the nation’s largest minority group will continue to grow in the coming decades.”


Census 2010: Apportionment Basics

The first numbers from the 2010 Census, to be released tomorrow, are the state population totals that have been the basis of the proportional division of seats in the House of Representatives since the nation’s early days. The number of House seats has been fixed at 435 since 1913, but there have been numerous tweaks in the methodology used to divide them up—and debate continues today.

The U.S. Constitution requires that a census be taken every 10 years in order to divide the House of Representatives “among the several States according to their respective numbers, counting the whole number of persons in each State,” except for slaves, who, until the late 1800s, were counted as three-fifths of a person, and certain Indians. Under federal law, the Census Bureau must deliver population totals to the president nine months after Census Day, which now means the deadline is Dec. 31. The reapportioned Congress will convene in 2013.

The first numbers for each state will include a total of residents, as well as an apportionment count that will also include any members of the military or federal employees overseas (and any dependents living with them) who can be allocated back to a particular state. In 2000, more than half a million Americans overseas were included in state apportionment counts. These overseas Americans also were included in the apportionment counts from the 1970 and 1990 censuses. (They won’t be included in the set of totals that are used to redistrict within states.)

Evaluating How Census 2010 Reached Hard-to-Count Groups

The Census Bureau did a better job in 2010 than it had in 2000 reaching out to “hard-to-count” groups, such as minorities and renters, who are more likely to be missed by census-takers than other Americans, according to a report released this week by the Government Accountability Office. The bureau’s outreach included a massive targeted advertising campaign, partnerships with thousands of community organizations, and special counts at institutions such as soup kitchens.

The report, one of three census evaluations released by GAO the week before the Census Bureau is scheduled to publish the first numbers from the 2010 Census, had general praise for the bureau’s outreach efforts (especially the advertising campaign), but noted some faults. It cited a balky and hard-to-use database used by the partnership staff. The report also quoted some census officials who said there was poor coordination between the local offices managing the count in their area and the outreach staff who were assigned to their localities. The Be Counted/Questionnaire Assistance Center program, which provided questionnaires at 38,000 staffed and unstaffed locations, returned and checked in an average of only 20 forms per site, indicating an operation that “was very resource intensive relative to the number of forms that were returned.”

The GAO noted that the Census Bureau is itself evaluating various aspects of its outreach campaign, with results expected in 2012, so the full impact of its efforts is not yet known. But the report stated, “the Bureau’s rigorous effort to raise awareness, encourage participation, and enumerate HTC (hard-to-count) populations likely played a key role in holding mail participation rates steady in 2010 for the overall population, a significant achievement given the various factors that were acting against an acceptable mail response in 2010.”


Cell Phone Challenge for the Census

A newly released Government Accountability Office review of Census Bureau follow-up efforts to reduce errors in the 2010 Census raises an issue that is familiar to survey researchers: The problem of reaching the growing share of Americans who only have cell phones and not landlines. Although the 2010 Census was mainly a mailback operation, the Census Bureau also telephoned nearly 7.4 million households to seek clarification of confusing or potentially incorrect information on their census forms.

This operation, called Coverage Follow-up (CFU), was completed on schedule and under budget, GAO concluded in a report that was one of three evaluations released by the agency the week before the Census Bureau is scheduled to publish the first counts from the 2010 Census. The GAO evaluation also found the bureau completed another follow-up task, Field Verification, on time and under budget. But the agency’s evaluations raised questions about some aspects of the design of both operations, which had as their goal a reduction in the number of Americans who were missed, counted more than once or counted in the wrong place by the 2010 Census.

The problems encountered with telephone follow-up were among a number of issues discussed in the GAO report, but they are the focus of this posting because they are relevant to any research that relies on reaching respondents by telephone. As GAO points out, the National Center for Health Statistics has found that more than 24% of U.S. households only use wireless telephones, not landlines, and work by the Pew Research Center also has found that when survey-takers only call landlines, it can skew their results. Including cell phones in a survey sample adds significantly to the cost and complexity of conducting research.

In the Coverage Follow-up operation, the Census Bureau contacted households with census form problems by telephone, which enabled it to reach more households than it would have been able to with more expensive in-person visits. It also used a commercial database to identify landline phone numbers that were missing or not valid, so as to target its calls more effectively. The Census Bureau only used landlines from the commercial database “due to concerns about not knowing the geographic location of wireless phones it might dial and the possible financial burden on wireless customers of unsolicited calls,” the GAO report said.

GAO: 2010 Census Operations Successful, But Fundamental Design Needs Reform

A few days before the Census Bureau is scheduled to release the first population totals from the 2010 Census, the Government Accountability Office published three reports evaluating key operations of the decennial count. In a letter to Congress summarizing its findings, the agency pronounced the 2010 Census “operationally successful,” but also suggested that the basic census  design “is no longer capable of delivering a cost-effective headcount.”

One of GAO’s reports on the 2010 Census evaluates the the non-response followup operation and other key field operations, and looks ahead to reforms for the 2020 Census. A second report examines several follow-up operations intended to reduce errors from the original count. A third GAO report looks at outreach and enumeration programs for “hard-to-count” populations such as immigrants and the homeless. This posting describes the first report; subsequent postings will explore the other two.

Here are some key sentences, from its letter to Congress, summarizing GAO’s conclusions in the first report: “Although some additional work and more data releases lie ahead, and information on the accuracy of the count is not scheduled to be available until early 2012, this much is clear: The Bureau generally completed the enumeration phase of the 2010 Census on schedule and consistent with its operational plans, and largely surmounted a series of risks that jeopardized the success of the headcount…an operationally successful census was no small accomplishment.”

However, the letter notes, “the 2010 Census required an unprecedented commitment of resources, including recruiting more than 3.8 million total applicants–roughly equivalent to the entire population of Oregon–for its temporary workforce; and it escalated in cost from an initial estimate of $11.3 billion in 2001 to around $13 billion, the most expensive population count in our nation’s history.

“Further, our oversight of the 1990, 2000, and now 2010 Censuses suggests that the fundamental design of the enumeration–in many ways unchanged since 1970–is no longer capable of delivering a cost-effective headcount given the nation’s increasing diversity and other sociodemographic trends.” Read more
