In France while the overall union density is 8%, in companies over 50 employees this level reaches 43%. US Bureau of Labor in 2010 notes a difference of median income of 200 dollars between union-members (917), and non-union members (717) without indicating if higher salaries link to more unionisation, or the reverse or in mutuality.

The number of people who are covered by collective agreements is higher than the number of union members (or the "union density" rate), and in many cases substantially higher, because when trade unions make collective agreements they aim to cover everyone at work, even those who have not necessarily joined for membership.
Over the same period during which union density in the US declined from 23.5 percent to 12.4 percent, some countries saw even steeper drops. Australian unionization fell from 50.2 percent in 1970 to 22.9 percent in 2003, in New Zealand it dropped from 55.2 percent to 22.1 percent, and in Austria union participation fell from 62.8 percent down ...
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans , but sometimes to other living organisms too. It is a key geographical term.
The model then uses birth, death, immigration, extinction and speciation to modify community composition over time. Hubbell's theta. The UNTB model produces a dimensionless "fundamental biodiversity" number, θ, which is derived using the formula: θ = 2J m v. where:
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.
If N 1 is the number of individuals at time 1 then = + + where N 0 is the number of individuals at time 0, B is the number of individuals born, D the number that died, I the number that immigrated, and E the number that emigrated between time 0 and time 1. If we measure these rates over many time intervals, we can determine how a population's ...
