Which of the following best defines population density in the context of India’s demographic studies?
निम्नलिखित में से कौन-सा भारत के जनसांख्यिकीय अध्ययनों के संदर्भ में जनसंख्या घनत्व को सर्वोत्तम रूप से परिभाषित करता हैं?
Detailed Solution & Logic
The number of persons per unit area of land/ भूमि के एकाई क्षेत्र में रहने वाले व्यक्तियों की संख्या
-
Population density measures how crowded a country or region is. It is defined as the number of people living per square kilometer (or unit area) of land.
-
Formula:
Population density = $\frac{Total Population}{Total land Area ({km}^2)}$-
In India, population density varies widely. For example:
-
Bihar – very high density (over 1,100 persons/km²)
-
Ladakh – very low density (about 3 persons/km²)
-
-
Knowing population density helps in resource planning, urban development, health services, and disaster management.
हिन्दी:
-
जनसंख्या घनत्व यह बताता है कि किसी देश या क्षेत्र में कितने लोग प्रति इकाई क्षेत्र में रहते हैं।
- सूत्र:
जनसंख्या घनत्व = $\frac{कुल जनसंख्या }{कुल भूमि क्षेत्र ({km}^2)}$
-
भारत में जनसंख्या घनत्व बहुत भिन्न है:
-
बिहार – बहुत अधिक घनत्व (1,100 से अधिक व्यक्ति/वर्ग किमी)
-
लद्दाख – बहुत कम घनत्व (लगभग 3 व्यक्ति/वर्ग किमी)
-
-
जनसंख्या घनत्व जानना संसाधन योजना, शहरी विकास, स्वास्थ्य सेवाओं और आपदा प्रबंधन में मदद करता है।
Extra Facts / अतिरिक्त तथ्य
-
India’s average population density (2011 Census) – 382 persons per km²
-
Highest density state – Bihar
-
Lowest density state – Ladakh
-
Population density affects infrastructure, education, and environmental management.
