Studies concerned with demographic methods and with methods from other disciplines that have been applied to demographic data as a whole. Includes mathematical demography and studies on methods of estimation and indirect estimation. Methodological studies and models concerned with one demographic variable, such as migration, are coded under the category concerned with that topic and cross-referenced to this heading. Studies on models used to investigate relationships between demographic variables and for the analysis of empirical data are also coded under this heading.

Examination of "early mortality exclusion" as an approach
to control for confounding by occult disease in epidemiologic studies
of mortality risk factors. American Journal of Epidemiology, Vol.
146, No. 8, Oct 15, 1997. 672-80 pp. Baltimore, Maryland. In Eng.
This study concerns methods for estimating the effects of chronic
disease risks on mortality, and examines the suggestion that subjects
dying during the first years of follow-up should be excluded from the
statistical analysis. "In this paper, we show that, when
confounding due to preexisting disease is present at the start of
follow-up, excluding subjects who die in the first few years of
follow-up does not necessarily reduce that confounding. Moreover, such
exclusion can even exacerbate the bias in the estimate of the effect of
exposure."

a data collection method designed for dynamic multilevel modeling.
Sociological Methodology, Vol. 27, 1997. 355-92 pp. Washington, D.C. In
Eng.
"This paper presents a new data collection method, called
the Neighborhood History Calendar, designed to collect event histories
of community-level changes over time. We discuss the need for and the
uses of this method. We describe issues related to the design of
instruments, collection of data, and data entry. We provide detailed
examples from an application of this method to the study of marriage,
contraception, and fertility in rural Nepal. The paper addresses
applications of this same technique to other settings and research
problems. We also extend the technique to collection of other forms of
contextual-history data, including school histories and health service
histories. Finally, we discuss how Geographic Information System (GIS)
technology can be used to link together multiple sources of
contextual-history data."

Adjusting for attrition in event-history analysis.
Sociological Methodology, Vol. 27, 1997. 393-416 pp. Washington, D.C.
In Eng.
"This paper will investigate the issue of weighting
for panel attrition in event-history models by comparing alternative
treatments of sampling weights in a divorce model for members of the
1986 [U.S.] Survey of Income and Program Participation (SIPP). Three
distinct weighting procedures are compared. These are based on (1) the
initial selection probability weights; (2) the 1986 SIPP panel weights;
and (3) the monthly attrition-adjusted weights. The paper also compares
these weighted estimates with the estimates of a structural model in
which attrition is treated as an error-correlated competing alternative
to divorce." The results indicate that in many instances divorces
in the SIPP end up being recorded as attrition.
