Open research questions in Census and Population Estimation
118 gap statements mined from Census and Population Estimation papers in our 4.5M-paper local library, which holds 1,196 papers on the topic — drawn mostly from each paper's own stated research gap, future-work, challenge and limitation notes, and its abstract. The ones listed below are a selection still marked open; each names the study that raised it, with a DOI link where the paper has one.
What the literature leaves open
Finally, we theoretically analyze discretization bias, show that calibrated continuous models are insufficient to eliminate it, and that an approach such as ours is necessary.
These methods are scattered across the literature, and an extensive overview of their assumptions, methodology, and performance is currently lacking.
The analysis is limited to Australia's small-area population estimates. The method's performance is affected by the COVID-19 pandemic. The analysis uses a specific set of data and methods.
Assessing the cohort-component method in Australia’s official small area population estimates · 2026 · DOIFuture research should continue to assess the cohort-component method in different contexts. The impact of the COVID-19 pandemic on small-area population estimates should be further studied.
Assessing the cohort-component method in Australia’s official small area population estimates · 2026 · DOIThe paper identifies a need for a precise primary formulation of key concepts and steps in statistical data processing. The authors aim to provide an overview of statistical concepts and methods in behavioral and social science research.
There is a need for statistical inference procedures for the parameters of two Xgamma populations under a joint progressive Type-II censoring scheme. The existing censoring schemes may not be suitable for many practical situations.
Inference for two xgamma populations based on joint progressive type-II censored samples · 2026 · DOIOur method assumes that the distributions of the number of reports per group member are similarly shaped for both the target and reference groups—specifically, that the ratio of the variance to the square of the mean is approximately equal across groups—even when the target group’s mean and full distribution remain unknown.
Estimating unknown populations from informant reports using scale-up reference groups and capture-recapture inference · 2026 · DOIThe application of CR to IPF epidemiology could be further investigated in health systems with greater overlap of patients utilizing more than one system.
As the resources of transition society are scarce, the organisation and processes had to be organised as effectively as possible in order to cope with a large-scope statistical programme of the EU.
Transformation of Estonian statistical system to the European statistical system - main aspects and experiences · 2011 · DOINow in its fourth year and with 100% of units in England taking part, the Count Me In census offers comprehensive but limited information on all people receiving inpatient psychiatric care.
There was a gap in the development of statistics in France due to insufficient flexibility in academic organisations, - The paper identifies a need to study the impact of historical events on statistical activity.
The statistician's role in society: The institutional establishment of statistics in France · 1987 · DOIThe identification of the need to develop ways of evaluating the accuracy of population registers using internal and external evidence.
Report and Summary: “Conference on Methods for Using Population Registers in Historical Research” Umeå University, Sweden August 12—17, 1984 · 1985 · DOIThe need to develop ways of evaluating the accuracy of population registers using internal and external evidence. The lack of theoretical literature about record linkage in situations where multiple sources are linked together.
Report and Summary: “Conference on Methods for Using Population Registers in Historical Research” Umeå University, Sweden August 12—17, 1984 · 1985 · DOIFurther testing of Jackson's method is needed. The method should be applied to real-world data. The effects of high levels of movement should be further studied.
The problem of confounding death and emigration in mark-recapture data is not adequately addressed. Jackson's method is proposed as a solution to this problem.
The need for population projections that can be used for planning purposes. The lack of user-friendly programs for population projections. The importance of evaluating the significance of the output.
In a national testing programme, such practical criteria are absent and statistical criteria must be employed; if there is no agreement upon the criteria, and the logical objections against the fit of the model are strong, the model cannot be accepted as providing an adequate basis for assessment.
The conventional chi-square test has limitations for analyzing multivariate contingency tables. Discrete multivariate analysis has not been incorporated to a significant extent into historical research.
Further research could explore the application of the technique to real-world populations. Further research could investigate the limitations of the technique in detail.
The paper highlights the need for repeated sampling for reliable estimates.
The paper suggests that future research should focus on injecting more standardization into the analysis of results of reconstitution studies. The paper also suggests that future research should explore the complementarity of aggregate, regional, and local case studies.
The paper identifies a gap in the field of historical demography, noting that the attempt to summarize the current state of local and regional studies may impose a false aura of homogeneity on what remains an exuberantly heterodox field. The paper also notes that there is a need for more standardization in the analysis of results of reconstitution studies.
The paper suggests that a similar analysis could be done for the 1990 or 1985 census. The paper suggests that benefit-cost analysis could be used for other types of data programs.
However, the performance of these models has not been tested thoroughly and prior…
Performance of generalized distance sampling models with temporary emigration: a simulation study · 2025 · DOIFurther research can be conducted to explore other censoring schemes, - Other lifetime distributions can be investigated using the proposed…
Inference for two xgamma populations based on joint progressive type-II censored samples · 2026 · DOI
