The population increased by 100000*.6=<<100000*.6=60000>>60,000 from births
They lost 2000*10=<<2000*10=20000>>20,000 people from emigration
They gained 2500*10=<<2500*10=25000>>25,000 people from immigration
That means the net increase from people moving was 25000-20000=<<25000-20000=5000>>5,000
So the total population is 100,000+60,000+5,000=<<100000+60000+5000=165000>>165,000
#### 165,000
