Simple Explanation
Population density calculation का basic formula same रहता है, लेकिन data boundary और reference year बदलने से numerator or denominator बदल सकते हैं। One source municipal limits use कर सकता है, another metropolitan area, और population counts भी different years के हो सकते हैं। इसलिए दूसरा विकल्प सही है। परीक्षा में density comparison करते समय spatial boundary and time reference check करें। / The basic population-density formula remains the same, but different boundaries and reference years can change the numerator or denominator. One source may use municipal limits while another uses a metropolitan area, and population counts may come from different years. Therefore, the second option is correct. In examinations, check spatial boundaries and time references before comparing density values.
