ABSTRACT
This working paper discusses the methodology and assumptions used to develop the recently released
projections of the population of the United States from 1999 to 2100. The new series includes projections
of the population by single year of age, sex, race, Hispanic origin, and nativity. While the basic
methodology used to produce these projections is the same as in earlier Census Bureau national population
projections, there have been changes, in both the time horizon and reference dates of the projections, as well
as in the specific methods used to estimate population change. The extension of the series to 2100 carries
the projections 20 years further into the future than any series previously issued by the Census Bureau.
For the first time, projection results include a break on nativity, defined dichotomously by the presence or
absence of U.S. citizenship at birth, as well as its cross-classification with other variables. Also new with
this series is the projection to quarterly reference dates, allowing users to view the national population
seasonally, or simply to select annual reference dates other than July 1. In addition, international migration
in the new series is allowed to vary over time, remaining somewhat lower than the constant value in the
previous series for the first two decades of the century, but reaching considerably higher levels than in the
previous one after 2020. Fertility rates in both models are allowed to change very little over time.
However, fertility rates by race and Hispanic origin are allowed to converge in the new middle series,
whereas in the previous middle series they remained constant within race and origin category. Finally, the
new mortality assumptions show more improvement in life expectancy for all racial and Hispanic origin
groups, except the non-Hispanic White population, than did the assumptions of the previous projection
series.

Abstract
Early in 2003 the transportation community contracted with the Census Bureau to produce the CTPP2000, a special tabulation. A special tabulation is made up of user defined tables and falls outside the "standard" products distributed by the Census Bureau like SF1, SF3, and PUMS. With the 2000 decennial data, the Census Bureau required all special tabulations to have disclosure avoidance techniques applied to them. For CTPP2000 this meant the institution of rounding and threshold techniques in addition to the already applied procedures of data swapping and imputation.
The specific disclosure rules for the American Community Survey after 5 years of data collection are likely to be similar, if not stricter than to those used for CTPP2000. In this paper the effects of rounding and thresholds on the CTPP will be exposed along with an examination of their effects under the American Community Survey. CTPP2000, ACS, 1990 CTPP and the NCHRP 8-48 data sets are used in this analysis.
We show how the rounding rules cause an undercount in the published datasets. The rounding rules for CTPP2000 could have worked better had the underlying data been more closely examined for the frequency of occurrence of cell values before the rounding decision was made. Finally, we show that a minor tweaking of the rules could have produced a more consistent dataset.
As for thresholds, they will always cause severe data loss even at a medium level of geographic aggregation, let alone for small geography. Compounding the severe data loss, consider that the number of observations in a 5 year accumulated ACS will be at least 25 percent smaller than those collected from the decennial census.
The purpose of this page is to provide Bay Area data users with easy access to CTPP data and documentation. The CTPP is a special product produced by the U.S. Bureau of the Census for the transportation community. More information on the CTPP is available at the links provided at the bottom of this page.
The CTPP comprises three elements: Part 1 provides tabular data by area of residence; Part 2 provides data by area of work; and Part 3 provides commuter "flow" data from area of residence to area of work. Data is available at various geographic "summary levels" including county, places (above 2,500 population), census tracts (1,405 in Bay Area), block groups (4,422 in Bay Area), census travel analysis zones (4,069 in Bay Area), and 5% PUMAs (54 in Bay Area).
The CTPP Part 1 data for California was received July 9th, 2003.
The CTPP Part 2 data for California was received January 11, 2004. The data CD that was received on 1/11/04 contains only ASCII data and SAS jobs to analyze the datasets.
The CTPP Part 3 dataset for California was released May 6, 2004. Part 3 data contains the county-to-county, place-to-place, tract-to-tract, etc., data.
Our intent is to provide CTPP data in common data formats. We are providing data in "csv" (comma-separated value) formats for importing into spreadsheet and database applications, and we are providing data in ESRI "shp" file format for use in ArcView or ArcGIS software. Note that some of the "dbf" files associated with the "shp" files are very large with several thousand variables, and cannot be used in MS-Excel.
About the NPTS
The National Household Travel Survey (NHTS) previously called the Nationwide Personal Transportation Survey (NPTS) serves as the nation's inventory of daily personal travel. It is the only authoritative source of national data on daily trips including purpose of the trip, means of transportation, how long the trip took, day of the week and month, number of people on the trip etc.
NYSDOT Add-on sample
In 1995 and again in 2001, the New York State Department of Transportation participated with Federal Highway Administration as one of several add-on areas. That is, NYSDOT purchased additional household samples to increase the coverage and reliability of the NPTS data for analysis of the travel patterns of residents within New York State. The 1995 survey was conducted from May 1995 to July 1996, the 2001 survey from April 2000 to May 2001.

Journey To Work (JTW)
The journey to work and related questions are asked on the decennial census long form. In 1990 these data appear in Census Summary tape File #3 (STF3) and in 2000 on Census Summary File #3 (SF3). Tabulations, called the 1990 and the 2000 "Census Transportation Planning Package (CTPP)" were created for transportation analysts from these files. The CTPP has three components, a residential summary, a work place summary and a flow based summary. Most of the questions received regarding Journey to Work have been focused on the mode used and the average travel time. To this end, two interactive databases have been developed to allow users to select residence origin(s) and workplace destination(s) at the county or place level and obtain residence or workplace summaries for mode used and average travel time to work.
The 1990 application is based on the 1990 CTPP Part C, means of transportation to work table which did not contain the field “work at home.” The 2000 application is based on the 2000 CTPP Part 3 means of transportation to work table which does contain the field “work at home” whenever the origin (residence) and the destination (workplace) geography are the same. What this means is that in 1990 the workers who “work at home” need to be added to the 1990 flow data, whenever the origin and destination locations are the same, if a correct comparison is to be made with 2000.
A table exists at this location that compares 2000 with 1990 whenever the geography in 2000 matches 1990. This table contains work at home in 2000 and 1990. The reader should add the 1990 values for “workers at home” to the 1990 flow data (from the application) whenever the origin and workplace geography are the same.
Same sex and unmarried partner household data are collected for those households where the householder and his or her partner are not married, but are living in a close personal relationship. An unmarried partner can be of the same sex or opposite sex of the householder.
An unmarried partner, in an unmarried partner household, is an adult who is unrelated to the householder, but shares living quarters and has a close personal relationship with the householder. This relationship is based on the self-identification of respondents.
Here are some sources for your use:
- The American FactFinder contains two sources:
- American Community Survey Table B11009, shows "Unmarried Partner Households by Sex of Partner."
- Census 2000, Summary File (SF) 1 Table PCT14, "Unmarried Partner Households by Sex of Partner" is available for the nation, state, metropolitan statistical area, city/place, county, and various other geographies.
- Additionally, same-sex unmarried partner household data were collected in the 1990 Census. The Technical Note on Same-Sex Unmarried Partner Data From the 1990 and 2000 Censuses provides guidance on comparing these data.
- The Census 2000 special reports include:
- Population and Housing Table, PHC-T-19, Hispanic Origin and Race of Coupled Households provides race and gender for unmarried partner households for the U.S.
- The Census Bureau also collects data for same sex and unmarried partner households in ongoing survey programs, but does not regularly produce tabulations on this topic.

Across the country, the income gap between blacks and whites remains wide, and nowhere more so than in Manhattan. But just a river away, a very different story is unfolding.
In Queens, the median income among black households, nearing $52,000 a year, has surpassed that of whites in 2005, an analysis of new census data shows. No other county in the country with a population over 65,000 can make that claim. The gains among blacks in Queens, the city’s quintessential middle-class borough, were driven largely by the growth of two-parent families and the successes of immigrants from the West Indies. Many live in tidy homes in verdant enclaves like Cambria Heights, Rosedale and Laurelton, just west of the Cross Island Parkway and the border with Nassau County.

If you think it's taking longer than ever to get to work, you're right.
The Census Bureau says New York City now has the second-longest commute in the nation - 34.2 minutes - a slight increase over the past five years and only a little better than Baltimore.
The average commute for the rest of the country is 25.5 minutes - a 24-second drop since 2005.

TECHNICAL NOTE ON SAME-SEX UNMARRIED PARTNER DATA FROM THE 1990 AND 2000 CENSUSES
...In 1990, the edit and allocation procedures did not allow same-sex “spouse” combinations to occur, thus resulting in the allocation of one of these two items in order to achieve editing consistency among the responses.
...Processing steps were changed for Census 2000 for households that contained same-sex “spouses.” If the person with the “spouse” category was the same sex as the householder and if neither person had their sex previously allocated, a relationship response of “spouse” was allocated as an “unmarried partner” response.
...Two principal factors affected our decision to take this approach for Census 2000.
1. Marriage Act (H.R. 3396) passed by the 104th Congress. This act instructs all federal agencies only to recognize opposite-sex marriages for the purposes of enacting any agency programs. In order for Census Bureau data to be consistent with this act and the data requirements of other federal agencies, same-sex spouse responses were invalidated. The legislation defines marriage and spouse as follows:
“In determining the meaning of any Act of Congress, or of any ruling, regulation or interpretation of the various administrative bureaus and agencies of the United States, the word ’marriage’ means only a legal union between one man and one woman as husband and wife, and the word ’spouse’ refers only to a person of the opposite sex who is a husband or wife.” In order for the Census Bureau to be consistent with this act and the data requirements of other federal agencies, same-sex “spouse” responses were invalidated.
2. The second factor took into consideration that couples in long term same-sex relationships may consider themselves as “married partners” and thus respond as such on the census form. In addition, at the time of writing the editing program for Census 2000, there were several challenges in the courts concerning the legality of same-sex marriages. Clearly, we could not ignore the fact that same-sex spouse responses were going to be recorded during Census 2000. In light of these social and legal aspects and the lack of a key variable in the statistical allocation routine (marital status) the assignment of same-sex “married” couples to the same-sex “unmarried partner” category was the procedure chosen for the editing process. We were adverse to a randomized allocation of these responses after people had clearly marked a close relationship preference on the census form.
As a result of these changes in the processing routine, estimates of same-sex unmarried partners are not comparable between the 1990 and 2000 census.
