How to approach

First, extract and tabulate the population data for urban and rural males and females across States A, B, C, and D, computing total populations for each state. Then, systematically compute the required proportions, ratios, and percentages for parts (a) through (e) with clear formulas, concluding each section with a definitive answer.

Introduction

Statistical interpretation of demographic data involves extracting discrete segment values across geographic units and applying standard proportional and ratio analyses. Based on the data for the population aged above 60 across States A, B, C, and D, calculations can be systematically performed to evaluate urban-rural distribution and gender balance.

1. Baseline Data Extraction

Compiling the demographic counts for the population aged above 60 across the four states:

  • State A: Urban Male (UM) = 1,600; Urban Female (UF) = 2,600; Rural Male (RM) = 3,200; Rural Female (RF) = 2,140. Total Population = 9,540.
  • State B: Urban Male (UM) = 3,100; Urban Female (UF) = 820; Rural Male (RM) = 3,800; Rural Female (RF) = 4,160. Total Population = 11,880.
  • State C: Urban Male (UM) = 940; Urban Female (UF) = 900; Rural Male (RM) = 1,840; Rural Female (RF) = 900. Total Population = 4,580.
  • State D: Urban Male (UM) = 3,490; Urban Female (UF) = 1,860; Rural Male (RM) = 5,820; Rural Female (RF) = 600. Total Population = 11,770.

(a) State with the Highest Proportion of Rural Females

Proportion = Rural Female Population / Total State Population

  • State A: 2,140 / 9,540 = 0.2243 (22.43%)
  • State B: 4,160 / 11,880 = 0.3501 (35.01%)
  • State C: 900 / 4,580 = 0.1965 (19.65%)
  • State D: 600 / 11,770 = 0.0509 (5.09%)

Conclusion: State B has the highest proportion of rural females to its total population at 35.01%.

(b) State with the Highest Urban-Rural Ratio of Males

Ratio = Urban Males / Rural Males

  • State A: 1,600 / 3,200 = 0.500
  • State B: 3,100 / 3,800 = 0.816
  • State C: 940 / 1,840 = 0.511
  • State D: 3,490 / 5,820 = 0.599

Conclusion: State B has the highest urban-rural ratio of males aged over 60 (0.816).

(c) State with the Lowest Male to Female Ratio in Urban Habitat

Ratio = Urban Males / Urban Females

  • State A: 1,600 / 2,600 = 0.615
  • State B: 3,100 / 820 = 3.780
  • State C: 940 / 900 = 1.044
  • State D: 3,490 / 1,860 = 1.876

Conclusion: State A has the lowest male to female ratio in the urban habitat (0.615).

(d) Gender with the Smallest Percentage Presence in Urban Habitat

Aggregate urban populations across all four states:

  • Total Urban Males: 1,600 + 3,100 + 940 + 3,490 = 9,130
  • Total Urban Females: 2,600 + 820 + 900 + 1,860 = 6,180
  • Total Urban Population: 9,130 + 6,180 = 15,310

Percentage shares:

  • Urban Male Share: (9,130 / 15,310) × 100 = 59.63%
  • Urban Female Share: (6,180 / 15,310) × 100 = 40.36%

Conclusion: Females have the smallest percentage presence in the urban habitat (40.36%).

(e) State with the Highest Percentage of Rural Males

Percentage = (Rural Males / Total Population of State) × 100

  • State A: (3,200 / 9,540) × 100 = 33.54%
  • State B: (3,800 / 11,880) × 100 = 31.98%
  • State C: (1,840 / 4,580) × 100 = 40.17%
  • State D: (5,820 / 11,770) × 100 = 49.44%

Conclusion: State D has the highest percentage of rural males to total population at 49.44% (and also when measured against total state males at 62.51%).

Conclusion

The step-by-step ratio and percentage calculations establish that State B leads in rural female concentration and male urbanisation, State A displays a female-dominant urban elderly demographic, females form the minority in total urban elderly population, and State D shows the highest rural male concentration.

Key facts to remember

definition
Urban-Rural Ratio

A demographic metric expressing the proportion of a subpopulation residing in urban areas compared directly to its counterpart in rural areas.

statistic

Across all four states, urban males aged over 60 constitute 59.63% (9,130) of the urban elderly population, while females constitute 40.36% (6,180).

Frequently asked questions

How is the proportion of a specific demographic cohort computed relative to total population?

The proportion is calculated by taking the specific cohort size (such as rural females) as the numerator and dividing it by the aggregate population of that state across all habitat and gender categories.
