Generalization — interpretation and analysis:
Several factors may have contributed to this change. Firstly, the family income has greatly increased and people have more spare money to deposit in the bank. Secondly, people want to deposit money to buy more expensive items such as houses and cars. Thirdly, banks are still thought of as the safest place to deposit money. More and more people are willing to deposit money in banks instead of other investment such as stock exchange and future investment.

Making a sound conclusion:
From the above table we can predict that the family income will continue to increase and that people will have even more money to deposit in the bank.
