Question

1. What proportion of newborns survive to age 2? Please show me how to calculate it!

Age	nx	dx	lx	mx	lxmx
0	100	35	1.00	0	0
1	65	?	0.65	0	0
2	45	15	?	3	1.35
3	30	20	0.30	1	?
4	10	10	0.10	1	0.10
5	0	0	0.00	1	0

Answer 1

Age specific survivorship = no of alive at given age/initial no at begining of time

So proportion of newborns survive at age2=no of alive at age2(nx2)/initial no at begining(nxo)= 45/100=0.45

dx1(death at age 1)=nx2(no of alive at Age2 )-nx1(no of alive at age1)=65-45=20

lxmx at age3=lx at age3 x mx at age =0.30x1=0.30

Complete Table

Age	nx	dx	lx	mx	lxmx
0	100	35	1.00	0	0
1	65	65-45=20	0.65	0	0
2	45	15	45/100=0.45	3	1.35
3	30	20	0.30	1	0.30x1=0.30
4	10	10	0.10	1	0.10
5	0	0	0.00	1	0
