Project Overview

This interactive dashboard explores the global burden of tuberculosis (TB) between 1990 and 2015. Built using Power BI, the dashboard presents a visual and analytical breakdown of TB's prevalence, incidence, and mortality across different world regions and countries.

Data Source

The dataset was sourced from the World Health Organization (WHO), specifically from the Tuberculosis Burden by Country. It includes estimated statistics for:

Total Population
TB Prevalence
TB Mortality
TB Incidence

Key Insights & Findings

      Global Totals (1990–2013):  
      Total Population: 149 Billion
TB Prevalence: 340.7 Million
TB Deaths: 44.35 Million
Incident Cases: 216 Million

    

India consistently leads in TB prevalence and TB-related deaths.
About 20.76% of TB deaths are HIV-related.
Average TB detection rate is highest in Europe (79%), and lowest in Africa (51%).
In 2013 alone: 7B population, 11.4M TB prevalence, 1.43M deaths, 8.96M incidents.

Observations

TB burden is highest in low-income and HIV-affected countries.
Strong regional disparities in detection and mortality rates.
Steady decline in TB deaths post-2001 due to interventions.
