The Committee for International Cooperation in National Research in Demography (CICNRED) is an organization focused on promoting and facilitating cooperation among countries in the field of demographic research. It serves as a platform for demographic researchers, policymakers, and institutions to share knowledge, data, and methodologies, with the aim of improving demographic research and its application in policy-making.

The "Crisis of the Late Middle Ages" refers to a period roughly spanning from the late 14th century to the early 16th century in Europe, characterized by a series of interconnected social, economic, political, and environmental challenges that significantly affected medieval society and set the stage for the transition to the Renaissance and the early modern period.

Agricultural censuses are comprehensive surveys conducted at regular intervals to collect data on the agricultural sector within a specific geographic area, such as a country or region. These censuses aim to gather information about various aspects of agriculture, including: 1. **Farm Structure**: Data on the number of farms, farm sizes, types of ownership, and organizational structures. 2. **Crop Production**: Information on the types and quantities of crops grown, planting practices, and land use.

A census is a systematic process of collecting, analyzing, and interpreting data about the population of a specific area, typically a country or region. It usually involves gathering information on various demographic characteristics, such as age, sex, ethnicity, occupation, education level, housing conditions, and more.

Demographics organizations refer to groups, institutions, or entities that collect, analyze, and disseminate data related to the characteristics of populations. This includes information about age, gender, race, ethnicity, income levels, education, employment, geographic location, and other social and economic factors. These organizations may operate in various sectors, including government, academia, non-profits, and the private sector.

Human populations refer to groups of individuals of the species Homo sapiens who inhabit specific geographic areas at a given time. These populations are characterized by various demographic attributes such as size, density, distribution, age structure, birth and death rates, and migration patterns. Key aspects of human populations include: 1. **Size**: The total number of individuals in a specific area or the global population, which is currently over 8 billion.

The Beverton-Holt model is a type of discrete-time mathematical model used in ecology and population dynamics to describe the growth of a population. It is particularly useful for modeling single-species populations under conditions of limited resources, where the population is subject to density-dependent factors.
