about
Sentier Research was established in 1997. At that time John Coder
ended a 25-year period of distinquished service with the United States Bureau of the
Census and founded Sentier Research.
While at the Census Bureau John played various roles in the Household
Economic Statistics Division including leading the group responsible producing and analyzing the
Nation's official income and poverty statistics. He also initiated programs to forecast household
income and to provide estimates of the lifetime earnings of American workers.
In addition, John pioneered the Small Area Income and Poverty Estimates Program that now supplies
household income and poverty estimates for states, counties, and school districts during
intercensal periods. He also played a leading role in development of the Survey of Income and
Program Participation.
In the international arena he helped to establish the Luxembourg
Income Study, a project that now maintains an extensive database of household surveys
covering income and demographic data for 29 countries.
For the past nine years Sentier Research has provided clients with high quality services related to
the collection, processing, and analyzing data on the American population with emphasis on demographics, income,
expenditures, and measures of household spending and purchasing power.
In the past several years Sentier has developed new methodologies to forecast trends in
household income and demographics to the year 2025.
Our microsimulation tax model that estimates federal, state, and payroll taxes based on the
the March Current Population Survey has been adopted by the Bureau of the Census.
Sentier also provides custom services such as design of
survey questionnaires, sampling frames, evaluations of survey data quality, cleaning
dirty survey data, imputing for missing responses, weighting survey observations, and design of web browser
interfaces for tabulating data from large-scale surveys. |
