Males had a median income of $40,389 versus $31,504 for females. The per capita income for the CDP was $23,476. 6.1% of the population and 4.4% of families were below the poverty line. Out of the total population, 7.3% of those under the age of 18 and 4.2% of those 65 and older were living below the poverty line.
Population estimates based on an initial settlement date of ca. AD 1150 and paleo-environmental evidence of early human impact on the land completely contradict the theory of constant population growth. Instead, the estimated population curve can be divided into three sections: pre-settlement, when no humans lived in Hawaii; the initial ...
Population estimates based on an initial discovery and settlement of Hawaii in around 1150 CE, a proposed growth rate at the highest in the world and reliance on the paleo-environmental evidence of early human impact on the land completely contradict the constant-population-growth theory. Instead the estimated population curve can be divided ...
A population exhibiting a weak Allee effect will possess a reduced per capita growth rate (directly related to individual fitness of the population) at lower population density or size. However, even at this low population size or density, the population will always exhibit a positive per capita growth rate.
Thomas Robert Malthus, after whom Malthusianism is named. Malthusianism is a theory that population growth is potentially exponential, according to the Malthusian growth model, while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population decline.
Zero population growth is often a goal of demographic planners and environmentalists who believe that reducing population growth is essential for the health of the ecosystem. Achieving ZPG in the short run is difficult because a country's population growth is often determined by economic factors, incidence of poverty, natural disasters, disease ...
But, over the past 130 years, the indigenous population has recovered and now makes up 45% of the 7,800 inhabitants of the island, also known as Rapa Nui – and part of Chile since 1888.
In the study of age-structured population growth, probably one of the most important equations is the Euler–Lotka equation.Based on the age demographic of females in the population and female births (since in many cases it is the females that are more limited in the ability to reproduce), this equation allows for an estimation of how a population is growing.
