The island has no permanent population. [1] It is one of the islands closest to the capital island Malé. Hulhulé is considered a ward of Malé. The 2.1-kilometre (1.3 mi) Sinamalé Bridge links the island with Malé. The bridge, which has two car lanes and separate lanes for motorcycles and pedestrians, opened on 30 August 2018.
Malé [a] is the capital and most populous city of the Maldives.With a population of 211,908 in 2022 [1] within its administrative area and coterminous geographical area of 8.30 square kilometres (3.20 sq mi), Malé is also one of the most densely populated cities in the world.
Lexis diagram showing the cohort of 2003-born persons in green, and the year 2005 in red. In demography, a Lexis diagram (named after economist and social scientist Wilhelm Lexis) is a two-dimensional diagram used to represent events (such as births or deaths) that occur to individuals belonging to different cohorts.
The first principle of population dynamics is widely regarded as the exponential law of Malthus, as modelled by the Malthusian growth model.The early period was dominated by demographic studies such as the work of Benjamin Gompertz and Pierre François Verhulst in the early 19th century, who refined and adjusted the Malthusian demographic model.
In statistics and econometrics, cross-sectional data is a type of data collected by observing many subjects (such as individuals, firms, countries, or regions) at a single point or period of time. Analysis of cross-sectional data usually consists of comparing the differences among selected subjects, typically with no regard to differences in time.
Accuracy of PVAs has been tested in a few retrospective studies. For example, a study comparing PVA model forecasts with the actual fate of 21 well-studied taxa, showed that growth rate projections are accurate, if input variables are based on sound data, but highlighted the importance of understanding density-dependence (Brook et al. 2000).

One of the most basic and milestone models of population growth was the logistic model of population growth formulated by Pierre François Verhulst in 1838. The logistic model takes the shape of a sigmoid curve and describes the growth of a population as exponential, followed by a decrease in growth, and bound by a carrying capacity due to ...
