Secondary Data Sources for Public Health

Abstract

Secondary data play an increasingly important role in epidemiology and public health research and practice; examples of secondary data sources include national surveys such as the BRFSS and NHIS, claims data for the Medicare and Medicaid systems, and public vital statistics records. Although a wealth of secondary data is available, it is not always easy to locate and access appropriate data to address a research or policy question. This practical guide circumvents these difficulties by providing an introduction to secondary data and issues specific to its management and analysis, followed by an enumeration of major sources of secondary data in the United States. Entries for each data source include the principal focus of the data, years for which it is available, history and methodology of the data collection process, and information about how to access the data and supporting materials, including relevant details about file structure and format.

Effect of Age in Second Language Acquisition: A Critical Review from the Perspective of Critical Period Hypothesis and Ultimate Attainment

“…Secondary data analysis, as described by Boslaugh (2007), "In the broadest sense, analysis of data collected by someone else" (p. 9). Secondary data analysis has been growing in popularity and was adopted by many researchers in their studies to discuss issues in SLA and other issues in linguistics (See- Ellis, 2010;DeKeyser, 2013;Karim & Rahman, 2016).…”

The Determinants of Public Education Expenditures: An Empirical Analysis of Changing Patterns and Growth of Public Expenditure on Education in Kenya

“…It is debated that collection of secondary data by individual scholars might not be credible and reliable particularly when it comes to government data on expenditures and budget. Boslaugh (2007) expounded that secondary data analysis usually contains analysis of data collected by someone else. According to Vartanian (2010), other than the initial purpose of the collected ISSN 2161-7104 2017 secondary data, this data can be used to answer other research questions.…”

The Combination of Agile and Lean in Software Development: An Experience Report Analysis

“…If it is undertaken with care and diligence, it can provide a cost-effective way of gaining a broad understanding of research questions. It is also often considered a starting point for other research methods, helpful in designing subsequent primary research and can provide a baseline with which to compare the primary data analysis results [17]. Given the exploratory nature and early stage of the study, secondary data analysis is considered a feasible way to build initial understanding of the phenomenon under the study.…”
