Which of the following best defines the 'Current Weekly Status' (CWS) used by…

Concept: The National Sample Survey Office assesses employment status using approaches that differ in their reference period and, where the period is a week, in how that week's activity is recorded: Usual Status uses a 365-day reference period and yields one status per person for the year; Current Weekly Status (CWS) uses a 7-day reference period preceding the survey date and yields one status per person for that week; Current Daily Status also uses that same 7-day reference week but instead assigns a separate activity status for each day within it.

Application: Applying this directly to the definition asked here: the option describing a single activity status assessed over the 7 days preceding the survey (rather than a status assigned separately for each day) is the one that matches the CWS definition, since CWS covers the week as a whole rather than day-by-day.

Cross-check: Checking the remaining reference-period lengths against NSSO's own framework confirms none of them describes CWS:

• A 365-day (one-year) reference period corresponds to Usual Status, not CWS.

• A 30-day (one-month) reference period is not one of NSSO's three standard reference periods for measuring activity status.

• Registration with an employment exchange is recorded in the exchange's own administrative register, a source entirely separate from NSSO's household activity-status survey.

• The single, week-as-a-whole framing in this option distinguishes it from Current Daily Status, which uses that same 7-day reference week but assigns a separate activity status to each individual day.

Result: Hence, the activity status based on the 7 days preceding the survey is the correct definition of Current Weekly Status.
