To facilitate demographic research, CSDE assists affiliates with collecting, clarifying, sorting, and analyzing statistics throughout the research process. To make a statistical consulting appointment, contact Cori Mar.

What We Offer


The CSDE Statistics Core offers statistical consulting to faculty, staff, and students studying demography. This includes the following services:services1

  • Assistance with study planning and design
  • Assistance with the choice and application of statistical methods
  • Advice on interpretation and presentation of statistical results
  • Assistance with statistical software
  • Development of specialized statistical methods

More specific services are outlined below; click each section for details.

CSDE can provide data analysis, as time permits, for short-term projects of CSDE faculty affiliates. In addition, we can supervise graduate students or research staff doing data analysis. Staff are also available to have some of their time “bought out” to do longer-term data analysis on grant-funded projects.

CSDE also provides the following data-management services:

  • Setup of data sets
  • Documentation and version-tracking
  • Data cleaning
  • Extraction of variables from larger data sets

CSDE can provide comprehensive grant-proposal support. For statistical grants, we can help with research conceptualization and design, perform preliminary and power analyses, and assist in writing the data-analysis section.

If you receive assistance from CSDE, we would appreciate you noting our partial support in the budget in order to help with the data management, data analysis, and/or statistical analyses of the research project.

CSDE can assist you in creating visual displays of your data for both exploratory and presentation purposes. We can create a publication-quality graphic to your detailed specifications, and we can help you design one from the concept stage as well.

We would also like to acknowledge Chris Adolph’s excellent CSSS class, Visualizing Data, and recommend it to anyone interested in this topic.



SAS is a computer program with a broad range of features for statistical analysis, data management, and graphics. It’s capable of efficiently handling very large datasets, including those with many observations and variables. It’s also highly flexible: its uses can range from simple descriptive computations to sophisticated applications development. For novices, though, its learning curve can be steep—a tutorial of some sort is recommended.
