## Overview
End-to-end health data analysis project using a simulated Nigeria Demographic and Health Survey (NDHS) dataset covering 5,000 respondents across all 36 states and FCT. The project explores maternal and child health indicators including facility delivery, antenatal care, immunization, and child nutrition.

## Key Analyses
| Script | What it does |
|--------|-------------|
| 00 | Generates 5,000-record NDHS dataset with 25+ variables |
| 01 | Cleans data, encodes factors, creates derived variables |
| 02 | National and zonal KPI summaries |
| 03 | 7 publication-quality ggplot2 charts |
| 04 | Chi-square, t-test, ANOVA, logistic regression, correlation |

## Visualizations Produced
1. Facility delivery rate by geopolitical zone (bar chart)
2. Health indicators by education level (grouped bar)
3. Immunization coverage heatmap by zone
4. Health utilisation by wealth index (combo chart)
5. Maternal age distribution by zone (density plot)
6. ANC visits vs facility delivery rate (scatter + regression)
7. Child malnutrition (stunting/wasting) by zone
