Expected yield rates are essential to a survey's data collection plan, as they inform requisite sample sizes to meet the survey's objectives. Given an overall expected yield rate for a self-administered mail survey, this short take describes a simple method for using the Census Planning Database to assign differential yield rates to lower-level…

This research note argues the outdoor adventure profession needs census research studies. Although conceptually simple, a census is a laborious process needing methodological guidance. This paper provides suggestions for conducting a census. Four previous outdoor adventure census projects are referenced. These, along with the U.S. Census, are used…

The authors discuss the use of surveys for collecting data from a population sample and emphasise the importance of being careful with the language of data collection. [For "The Data Files 5: Graphs for Exploring Relationships," see EJ1355504.]

This article presents a descriptive, critical analysis of the comparability of information concerning students, teachers, and school resources gathered by organisations within government jurisdiction, and the pitfalls for the unwary researcher using government data banks. Differences in the method of compiling information about citizens, and…

Better data is needed on disability in Global Partnership for Education (GPE) partner countries to understand the extent to which children with disabilities are excluded from education, so that countries can make evidence-based and inclusive education policy and plans, and progress can be monitored globally. As part of its work helping to build…

Geography provides context to the information collected, tabulated, and disseminated by the Census Bureau, whether data for the United States as a whole, a state, a congressional district, a county or city, or a census tract (roughly the size of a neighborhood). Geographers perform the activities necessary to update and maintain the geographic…

The UK census authorities have proposed guidance for the 2021 census indicating that the sex question may be answered according to subjective gender identity. This raises issues about the measurement of sex and gender identity which other data collection exercises are also contending with. This paper addresses the questions that have arisen…

This article replies to the responses to my article on "Sex and the Census: Why surveys should not conflate sex and gender identity". Fugard conflates sex itself with the characteristics associated with sex, such as finger length ratios, leading to the erroneous implication that binary sex is not a useful explanatory variable. Hines…

Counting the Cost of Difference' replies to Alice Sullivan's piece on gender auditing in the UK Census. While Sullivan argues that the proposed changes to audit gender identity will dilute the meaning of 'sex' and thus the needs of women, I suggest that auditing on self-declared gender in Census 2021 signals a move towards the further recognition…

Since data collection technologies has become a part of daily life, measurement and data requirements now permeate many state mathematics standards, beginning as early as kindergarten and extending through high school. For example, the Standards for Mathematical Content, recommend that kindergarteners "describe and compare measurable…

Measuring race and ethnicity for administrative data sets and then analyzing these data to understand racial/ethnic disparities present many logistical and theoretical challenges. In this chapter, we conduct a synthetic review of studies on how to effectively measure race/ethnicity for administrative data purposes and then utilize these measures…

Accurate, timely data on student outcomes and post-graduate earnings is a critical piece of any state effort to close equity gaps in college access and success, boost attainment statewide, and strategically align education and workforce goals. Unfortunately, in the absence of a federal student-level data network, states and other key stakeholders…

Collecting the perfect data to answer a research question is optimal but not always feasible. Sometimes existing data can be leveraged to answer some questions, but this opportunity comes with important potential pitfalls. To test the effect of early life exposures such as being born preterm or living in a materially deprived neighborhood on early…

The Illinois State Board of Education (ISBE) is urged to submit a report to the General Assembly by December 31, 2021, with information on the reviewed areas and recommendations on how to streamline the school data reporting and collecting systems of the State of Illinois. ISBE supports more than 200 software applications that were created in…

An increased focus on high-impact pedagogical practices at a small, residential, higher education institution led to a grant-funded project to gather and analyze multidimensional data on 10,155 residential foreclosures in central Illinois from 2006 to 2013. Student researchers applied skills gained through academic coursework to investigate a…
