For each country, it is used to calculate the sum of squares of the proportion of each immigrant population (IM i ) as a share of the total immigrant population (M).
The gang's numbers are minuscule in relation to the total immigrant population on Long Island (roughly half a million, over-all) and to the Salvadoran population in Suffolk County (about sixty thousand).
Since recent immigrants comprised roughly 15%% of the total immigrant population in 1950, if this coefficient only reflected recent immigration, the implied coefficient on the recent immigrant share would be 0.4 (=.06/.15).
The five biggest immigrant groups in Norway account for 30.3% of the total immigrant population and represent various different cultures, reasons for and timing of immigration to Norway.
Replacing the recent immigrant share with the total immigrant share and estimating specification (2) using the 1950 data produces a coefficient of about 0.06 for native whites.
Average estimates of the total immigrant population are two to three times higher than reality.
The figures were estimates for the deaths of Qatar's total immigrant population (numbering more than 1m) for whatever reasons: old age, diseases, strokes, heart attacks, suicides, road accidents and other accidents.
Firstly, we are studying intergenerational mobility among the total immigrant population as well as between different immigrant groups.
The horizontal axis shows the relative immigrant share ratio: the share of immigrants from country c that lived in the spatial unit s in the year t 0 divided by the share of total immigrants that lived in spatial unit s in the year t 0. Values larger than one imply that the sending country c is over-represented in the spatial unit s relative to the average total immigrant population.
The plot circles and solid line are similarly defined in Figure 3 with the exception that we weight by origin-specific total immigrant population size since our independent variable in this figure is based on Census data.
