To effectively communicate the public health impact of Female Genital Mutilation/Cutting (FGM/C) across different countries, it’s essential to present the data in a clear and informative way. Below are three suggested charts to include in your report on FGM/C.


1. Chart 1: Prevalence of FGM/C in Different Countries

  • Type of chart: Bar chart

  • X-axis variable: Country (Categorical data)

  • Y-axis variable: Prevalence of FGM/C (Percentage, continuous data)

  • Other variables:

    • Age group (optional): A grouped bar chart could display the prevalence of FGM/C by age group (for example, women aged 15-49) within each country. This would be represented as a categorical variable that groups the bars by age group.

This chart would allow you to compare the prevalence of FGM/C across the 29 countries, highlighting countries with high rates of FGM/C and those where it is less common.


2. Chart 2: FGM/C Prevalence by Region

  • Type of chart: Stacked bar chart (or pie chart if fewer regions)

  • X-axis variable: Region (Categorical data – e.g., East Africa, West Africa, etc.)

  • Y-axis variable: Percentage of women affected by FGM/C (Continuous data, percentage scale)

  • Other variables:

    • Sub-regions or specific countries (optional): Within each region, you could break the data down further by showing the contributions of different countries within that region.

This chart would give a regional overview of how FGM/C varies across broader geographic areas, helping to identify regional hotspots where the practice is most prevalent.


3. Chart 3: Trends in FGM/C Prevalence Over Time

  • Type of chart: Line chart

  • X-axis variable: Year (Time, continuous data)

  • Y-axis variable: Prevalence of FGM/C (Percentage, continuous data)

  • Other variables:

    • Country or Region (optional): Different lines can represent different countries or regions. This allows for comparisons over time, showing trends in the decline or persistence of FGM/C over multiple years.

This chart would help to show whether the prevalence of FGM/C is decreasing, increasing, or remaining stable over time in specific countries or regions, providing insight into the impact of interventions and policy changes.


Additional Notes for Reflection:

Each chart is designed to help convey different aspects of the FGM/C issue:

  • Bar charts help highlight comparisons across countries or regions.

  • Stacked bar or pie charts are useful for illustrating the distribution of prevalence by region.

  • Line charts are effective in showing trends and monitoring changes over time, which is crucial for understanding the effectiveness of efforts to combat FGM/C.

The visualizations in these charts will help stakeholders and policymakers to better understand the scope of FGM/C and identify areas where intervention is most urgently needed.
