Dear as i understand what you are trying to ask i would like to elaborate the same as follows:
For a common man there is only a single Account i.e. SAVING ACCOUNT but when we talk about the management point of view or as a Observer / Analyser there are two different terms i.e. Saving A/c and Regular Saving A/c
Regular Saving A/c refers to the Active Account having monthy transactions takes place within the A/c
Saving A/c refers to general category where the holder becomes active only oftenly say when we compare on the basis of 1 Year or 3 Year i.e. it is active on the basis 12 months or 36 months and not on monthly basis.
For instance i would like to give you latest reference with respect to the National Investments & Advisory Council has just released their notification relating to Post Office Saving Accounts on 11.11.2011 you can find that notification on Google. However in such a report it was analysed that only 16% Saving A/cs are Active i.e. Regular Savings A/cs based on 12 Months crieteria and another are Just a Saving A/c. However there is no need to specify a criteria for General Saving A/c because every Saving A/c is treated as dead if not operated for last 3 years i.e. atleast 1 transaction is required.
I think you got the point. For People it is only 1 term but it's a different terms for Analysers.
