राष्ट्रीय नमूना सर्वेक्षण संस्थेने मांडलेल्या नित्य स्थिती बेरोजगारीच्या संदर्भातील खालील विधानांपैकी कोणती विधाने खरी आहेत? (a) ही संज्ञा तीव्र बेरोजगारी दर्शवते. (b) ही वार्षिक संज्ञा आहे. (c) ही संज्ञा व्यक्ती दर दर्शवते. (d) ही संज्ञा काळ दर दर्शवते. पर्यायी उत्तरे :

The correct answer is Option B ((a), (b) and (c)).

Key Points:
• The National Sample Survey Office (NSSO) measures unemployment using three major concepts: Usual Principal Status (UPS), Current Weekly Status (CWS), and Current Daily Status (CDS).
• Usual Status (a & b): Measures chronic or long-term unemployment over a reference period of one year preceding the survey, making it an annual concept capturing structural/chronic joblessness.
• Person Rate (c): The Usual Status unemployment is measured as a person rate (the percentage of the population or labor force that remained unemployed for a major part of the year), *not* as a time rate (which is captured by CDS).
• Statement (d) is false: It is not a time rate (time rates measure person-days of unemployment like CDS).
• Therefore, statements (a), (b), and (c) are true, making option (2) correct.
• Key Takeaway: NSSO's usual status unemployment is an annual concept, indicates chronic unemployment, and is measured as a person rate.
