The average migration rate to Alberta from the rest of Canada for the comparison group was substantially higher in 1996 to 2000 (0.364%) compared with 1991 to 1995 (0.301%) but remained almost unchanged in the next five-year period (0.348%). For immigrants, however, the average migration rate from the rest of Canada was 20% higher in 2001 to 2005 than in 1996 to 2000 (0.271% compared with 0.226%).
It should be noted that because the overall probability of moving to anywhere but Alberta is higher than the probability of moving to Alberta, an equal marginal effect will have a proportionally greater effect on the probability of moving to Alberta. That is, if P(j=2)=0.1 and P(j=1)=0.01 then dy/dx=0.005 for both outcomes implies a 5% increase in probability for j=1 but a 50% increase in probability for j=2 associated with variable x.
