MHB What is the long-term percentage of city dwellers?

Click For Summary
The discussion focuses on the movement of populations between urban and rural areas, specifically examining the long-term percentage of city dwellers. Each year, 20% of rural residents move to cities, while 10% of city residents relocate to rural areas. In 2015, 50% of the population lived in cities, with calculations showing that by 2016, this percentage would rise to 55%, and by 2017, it would reach 58.5%. The main question remains how to determine the long-term percentage of city dwellers using transition matrix logic. The conversation emphasizes the need for a mathematical approach to find a stable population distribution over time.

Hi, I am having trouble with the following question, I've answered part a but I am not sure about part b:

Suppose each year 20% of people who live in the country move into the city, while 10% of the city people move into the country.
a) If in 2015, 50% of the population live in the cities, what are the population percentages in
(i) 2016
Pcountry= 45%


Pcity= 55%


(ii) 2017
Pcountry= 41.5%


Pcity= 58.5%

b) Find the long-term percentage of city dwellers.

Use the same logic as explained here:http://mathhelpboards.com/advanced-probability-statistics-19/transition-matrix-question-14207.html#post67359
 
First trick I learned this one a long time ago and have used it to entertain and amuse young kids. Ask your friend to write down a three-digit number without showing it to you. Then ask him or her to rearrange the digits to form a new three-digit number. After that, write whichever is the larger number above the other number, and then subtract the smaller from the larger, making sure that you don't see any of the numbers. Then ask the young "victim" to tell you any two of the digits of the...
