By age

Overview

The deep poverty by age group metrics provide insights into how a policy reform affects deep poverty rates for different age categories. These metrics are part of the EconomicImpact class and can be calculated for children, adults, seniors, and the overall population.

Available Metrics

  1. poverty/deep/child: Calculates the deep poverty rate for children.

  2. poverty/deep/adult: Calculates the deep poverty rate for adults.

  3. poverty/deep/senior: Calculates the deep poverty rate for seniors.

  4. poverty/deep/age/all: Calculates the overall deep poverty rate.

Metric Structure

Each metric returns a dictionary with the following keys:

  • baseline: The deep poverty rate before the reform.

  • reform: The deep poverty rate after the reform.

  • change: The percentage change in the deep poverty rate due to the reform.

All values are rounded to 1 decimal place for the baseline, reform, and change.

Example Usage

from policyengine import EconomicImpact

# Initialize the EconomicImpact class with a reform
impact = EconomicImpact(reform={
  "gov.hmrc.income_tax.rates.uk[0].rate": {
    "2024-01-01.2100-12-31": 0.55
  }
}, country="uk")

# Calculate deep poverty rates by age group
child_deep_poverty = impact.calculate("poverty/deep/child")
adult_deep_poverty = impact.calculate("poverty/deep/adult")
senior_deep_poverty = impact.calculate("poverty/deep/senior")
overall_deep_poverty = impact.calculate("poverty/deep/age/all")

# Print the results
print(f"Child deep poverty: {child_deep_poverty}")
print(f"Adult deep poverty: {adult_deep_poverty}")
print(f"Senior deep poverty: {senior_deep_poverty}")
print(f"Overall deep poverty: {overall_deep_poverty}")

output

Child deep poverty: {'baseline': 2.4, 'reform': 2.5, 'change': 0.7}
Adult deep poverty: {'baseline': 2.6, 'reform': 2.7, 'change': 3.9}
Senior deep poverty: {'baseline': 1.8, 'reform': 1.8, 'change': 0.5}
Overall deep poverty: {'baseline': 2.4, 'reform': 2.5, 'change': 2.7}

Interpretation

In this example:

  • The child deep poverty rate increases slightly from 2.4% to 2.5%, a 0.7% increase.

  • The adult deep poverty rate increases from 2.6% to 2.7%, a 3.9% increase.

  • The senior deep poverty rate remains stable at 1.8%, with a minimal 0.5% increase.

  • The overall deep poverty rate increases from 2.4% to 2.5%, a 2.7% increase.
