Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Longitudinal Studies01:26

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
Cross-Sectional Research01:50

Cross-Sectional Research

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
Population Growth00:57

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Surveys02:16

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Summary
This summary is machine-generated.

New weighting methods for the General Household Survey (GHS) improve fertility estimates. These updated weights reduce bias in Total Fertility Rate (TFR) and age-specific fertility rates for analyses from 1979-2007.

Area of Science:

  • Demography
  • Social Statistics
  • Survey Methodology

Background:

  • The General Household Survey (GHS) is a vital source of social and demographic data in the UK.
  • Accurate weighting is crucial for minimizing bias in survey estimates.
  • Previous GHS weighting methods required updates to reflect demographic changes and improve data quality.

Purpose of the Study:

  • To develop and validate new weighting methodologies for the General Household Survey (GHS) covering the period 1979-2007.
  • To provide specific weights for general GHS analyses and specialized analyses of family information data.
  • To assess the effectiveness of the new weights in improving fertility estimates.

Main Methods:

  • Calculation of two new sets of survey weights for the GHS (1979-2007).
  • Adoption of methodologies consistent with Office for National Statistics (ONS) practices since 1996.
  • Performance evaluation using Total Fertility Rate (TFR) estimation and comparison with vital registration statistics (1971-2007).

Main Results:

  • The new GHS weights demonstrate improved accuracy in estimating the Total Fertility Rate (TFR).
  • Bias reduction was observed in both aggregate TFR and age-specific fertility rates.
  • The developed weights enhance the reliability of demographic analyses derived from the GHS.

Conclusions:

  • The newly developed GHS weights offer a significant improvement for demographic research, particularly in fertility analysis.
  • These weights provide more accurate estimates for both general GHS data and specific family information modules.
  • The study confirms the utility of the updated weighting strategy for longitudinal survey data analysis.
