Did number of telephone subscriptions increase in 2010
compared to 2000?
In order to see whether the number of subscribers in 2010 has increased
or not I used the spreadsheet to determine if number of subscribers in 2010 is
bigger than 2000. Chart 2 and 3 show that numbers are both increased and
decreased.

3) Results and Conclusions
As the years pass number of subscribers in developing countries
increases. The same cannot be said in developed countries because their
growth seems to either slow down or become negative. Number of subscribers
in some countries began to decrease after 2000 probably because of mobile
phones. Just like every technological device in our life phone will continue to
become smaller and thus portable. Therefore we will reduce our reliance on
fixed-telephone as the time goes on.
