These statistics provide vacancy rates, homeownership rates, and characteristics of units available for occupancy for the U.S., regions, states and the 75 largest metropolitan areas.
State assessments are increasingly used as outcome measures for education evaluations, and such evaluations generally use pretest scores as control variables. The correlation between the pretest and outcome (posttest) measures is a factor in determining, among other things, a study's statistical power. This report examines variability in pretest-posttest correlation coefficients for state assessment data on samples of low-performing, average-performing, and proficient students to determine how sample characteristics (such as achievement level) affect pretest-posttest correlation coefficients.
The series launched with three working papers and will release future papers as they are ready on a regular basis. It will feature cutting-edge research from our health, human services, and survey and statistical experts on compelling issues across Mathematica's diverse topic areas. In addition to providing access to our most current work, the working papers will share some of the in-depth analyses behind our other publications. The papers are intended to encourage discussion before final peer review and possible publication. In keeping with Mathematica's high standards of quality, all working papers undergo a rigorous internal quality review.
Volumes 1 and 2 contain abstracts of a variety of surveys available for family science research. Volume 3 contains copies of about half of the instruments described in volumes 1 and 2. ISBN: 9780803972506
In the past decade, policymakers and researchers have become increasingly interested in social programs that promote and support healthy marriages. A growing body of research evidence suggests that marriage has benefits for families and children, including improved economic well-being and mental health, and that children raised in two-parent families perform better in school and have more positive developmental outcomes than children from single-parent families (Amato and Booth 1997; McLanahan and Sandefur 1994; Waite and Gallagher2000; Wood et al. 2007). Inspired in part by these potential benefits of marriage, a wide range of programs have been developed to encourage and support healthy marriages (Dion 2005).
