(1) most women do not begin reproducing immediately upon the onset of puberty, which itself does not occur at a fixed age; (2) some women with the potential to reproduce never do so; (3) some women become widowed and do not remarry; (4) various elements of social behaviour restrain ...
Population dynamics is a field of ecology that focuses on the size, composition, and distribution of populations and how these factors change over time. The composition of a population includes variables such as its age structure, sex ratio, and phenotyp...
(see Population Dynamics: Theory of Stable Populations), when calculated for an actual population it takes no account of prospective growth/decline resulting either from migration nor does it take account of the growth potential inherent in population age structure (see Population Dynamics: Momentum ...
In addition, a first three-step multivariate analysis permits the definition of three groups, closely related to the theoretical models proposed by Whatley: (a) Group 1 structure or biocoenosis, present either in Recent low- to medium-energy environments located in erosional coastal stretches and...
although methods such as principal component analysis and Isomap can uncover looped latent structures, these unsupervised learning algorithms tend to produce distorted circles, in the presence of noise, when applied on baseline data (that is, stable condition), which makes the definition of a radius...
(Hedrich et al., 2016). As there is no universal definition, this review adopts the World Health Organization’s (WHO) definition of older adults as aged 50 years and above (World Health Organization WHO, 2016). This definition was created with consideration of factors contributing to ...
More generally, while the basic demographic equation holds true by definition, the recording and counting of events (births, deaths, immigration, emigration) and the enumeration of the total population size are subject to error. Allowance needs to be made for error in the underlying statistics ...
