Increases or decreases the amount emigrating from the province in scope.

NB: While this does not increase the emigration rate, it does increase the emigration amount. Every month, the emigration chance tick hits, and if it hits a threshold (threshold percentage factors are in ..\common\pop_types.txt), this modifier will increase the amount that would emigrate from a certain pop. For example, if there is a non-accepted pop at 7 militancy and in a province that is not their core, they will most certainly hit the emigration threshold. Normally, only a few thousand at most per month would leave, however, if immigrant_push was set to, say, 100, it would increase the amount emigrating by a factor of 10,000. This would increase the emigration amount from the usual thousand or so, into the hundreds of thousands.

, -1 < n < 1. Not sure what the specific effect of the value of n is, might be percentage increase ex. n = 0.1 means that strata's life needs increase by 10%.
Modifier Icons
In the event_modifiers.txt file, you'll see that every modifier has an icon it displays—for country modifiers, this is the icon that appears in the diplomacy screen (the one over which you hover to get the description and modifiers text). For province modifiers, this is the icon that appears in the province detail screen. The number of the icon corresponds to the "placement" of the modifier in the modifiers.dds file (in the gfx\interface folder). So you could, conceivably, go to that file and count along the strip to see the number of the icon you want.
The thing to note, however, is that province modifiers and country modifiers actually work a bit differently. The country modifiers "skip" the first two icons on the strip (the gavels—you can't get either to appear as country modifier icons) and "icon = 1" for a country modifier is actually the green pie chart icon (and thus you can only go up to 18 rather than 20). The picture below displays this (using the icons form vanilla), with the first row being province modifiers and the second row being country modifiers:
