Population Atlas of the Netherlands

This concise population atlas of the Netherlands shows the population pyramid of the Netherlands and the regional distribution of the population of the Netherlands by municipality in the years 1795, 1850, 1900, 1950 and 2000.

The project aims to develop an interactive population atlas of the Netherlands based on the previously published Bevolkingsatlas van Nederland (Population Atlas of the Netherlands) compiled by NIDI. The interactive population atlas intends to describe both historical and current population trends in the Netherlands using maps, graphs and explanatory texts. The maps are presented in an interactive application. See more

Mortality tables are usually graduated for either practical or scientific purposes. The formulae, in which the mortality is expressed as a function of x (= age) are often of the type (Makeham's law):
   mx = A + B.cx (force of mortality)
with A, B and c as parameters. Finding the values of those parameters from the crude material is the hard part.
King-Hardy's method is a suitable way to transform this power function into a linear equation system; it is solved here by way of a least square K-runtime function.

When invoked, one will find four controls in the bottom part. The first two controls act like a spinbox, the two right most controls simulate the Windows-locator. The challenge is to find as large as possible ranges for making the "law" valid.
Later, famous methods came from Th.N. Thiele, published posthumously in 1910, and recent approaches and remarks can be found in W.J. Willemse
