+# Datacard for Lesotho Gender Indicators (1960-2024)
+
+This dataset contains a time-series of key gender indicators for Lesotho, spanning from 1960 to 2024. The data has been aggregated from multiple sources, cleaned, and processed into a single, analysis-ready CSV file.
+
+The raw data was sourced from **The World Bank** data portal. The original files were provided in Excel (.xls) format.
+
+- **Temporal Coverage**: 1960-2024
+- **Geographic Coverage**: Lesotho
+- **Format**: Comma-Separated Values (CSV)

+
+## Data Points (Features)
+
+The dataset includes the following gender indicators, with 'Year' serving as the primary date column:
+
+1. `contraceptive_prevalence_any_method_of_married_women_ages_15_49_`: Contraceptive prevalence, any method (% of married women ages 15-49)
+2. `proportion_of_seats_held_by_women_in_national_parliaments_`: Proportion of seats held by women in national parliaments (%)
+3. `school_enrollment_primary_and_secondary_gross_gender_parity_index_gpi_`: School enrollment, primary and secondary (gross), gender parity index (GPI)
+
+---
+
+## Data Preparation & Missing Data Handling
+
+The raw data was processed using a Python script to transform it into a clean, structured format. The key steps were:
+
+1.  **Filtering**: The data was filtered to include only records for 'Lesotho'.
+2.  **Reshaping**: The original wide-format data (years as columns) was melted into a long format.
+3.  **Merging**: Data from all indicator files was merged into a single DataFrame on 'Year'.
+4.  **Handling Missing Data**: Missing values (`NaN`) were filled using a two-step strategy: linear interpolation followed by a back-fill to handle any remaining gaps at the start of the series.
