The statement “Very Low Human Development Countries : 0·000 – 0·004 points on the index” is not correct.
The Human Development Index (HDI) ranges from 0 to 1. While the theoretical minimum is 0, actual observed HDI values for countries typically range from around 0.3 to over 0.9. A range of 0.000 – 0.004 is extremely narrow and not representative of any recognized category of Human Development, including the lowest ones. The typical classification ranges for HDI are much broader and start from significantly higher values for the lowest category (e.g., below 0.550 for Low Human Development in recent reports).
HDI categories and ranges have seen slight variations over time. However, the lowest recorded HDI for any country is significantly higher than 0.004. The standard categories are typically Low, Medium, High, and Very High Human Development, with score thresholds that group countries based on their progress in health, education, and income.
