The digital resource in question is "Tools for Demographic Estimation," an online manual developed through a joint project between the International Union for the Scientific Study of Population (IUSSP) and the United Nations Population Fund (UNFPA). This resource explicitly positions itself as a direct descendant of the United Nations' "Manual X: Indirect Techniques for Demographic Estimation" (1983) and the "2002 UN Manual of Adult Mortality Estimation," building on their methodologies to provide updated tools for analyzing demographic data, particularly in settings with incomplete or unreliable vital registration systems [1]. Hosted at demographicestimation.iussp.org, it offers interactive, open-access chapters on various estimation techniques, emphasizing indirect methods for fertility, mortality, and migration analysis. The project aims to assist demographers, researchers, and policymakers in low- and middle-income countries by incorporating modern computational approaches while maintaining the foundational principles of the earlier UN manuals [1].
Within this resource, the specific section focused on "Evaluation and correction of fertility data" addresses methods for assessing and adjusting reported age-specific fertility rates, including techniques to detect and correct biases such as age misreporting or underreporting. This section is authored by Thomas A. Moultrie and forms part of the fertility estimation chapters [2].
The full suggested citation for this section is: Moultrie, T.A. (2013). Evaluation and correction of fertility data.

Available at: https://demographicestimation.iussp.org/content/evaluation-and-correction-fertility-data [2].
This resource represents a significant evolution in demographic tools, enhancing accessibility through digital formats and Excel-based implementations for practical application in global population studies [1][2].

The digital resource is **“Tools for Demographic Estimation”**, a web-based manual produced under a joint **IUSSP–UNFPA** project, which states that it “**follows in a direct line of descent from UN Manual X (Indirect Techniques for Demographic Estimation) and the 2002 UN Manual of Adult Mortality Estimation**.”[6][8]
Within this resource, the requested section is the fertility sub‑module titled **“Evaluation and correction of fertility data.”**[7][2] It appears in the online “Fertility” part of *Tools for Demographic Estimation*, alongside “Introduction to fertility analysis” and other fertility-estimation chapters.[7]
The suggested citation given in the PDF volume *Tools for Demographic Estimation* is (body text adapted to the requested section):
