The (extrememly crude) method I used:

Make up whatever your immigration is going to be, accounting for "number
of 
people per ship x number of ships" and how attractive your planet is. 
Alarish is a high-tech libertarian paradise, which makes up for the lack
of 
air. Cibola is "just like home, but not crowded" if you're from certain 
parts of India or Africa. To get a plausible maximum, look at how many 
people were immigrating to the US during, say, the Potato Famine.
Picking a 
number entirely out of the air, let's say 40,000 per year.

Figure out what a maximum population growth rate will be, ie how many 
babies. This will be lower than you might expect--let's say 3% per year,

which is pretty high, as I recall.

So you have Year2Pop = Year1Pop * 1.03 + 40,000, and cycle that for as
many 
years as you wish.

I also flexed both the immigration and the birth rate, eg immigration
went 
up whenever there was a war from which I might get refugees.
