Article 4 is a broad social-rights article. It includes equality between women and men and recognizes rights related to family, children, health, housing, food, water, a healthy environment, culture, and physical culture and sport.
Because it covers many topics, Article 4 can feel crowded. For citizenship purposes, remember it as the article of equality between women and men and many basic social rights, especially health, family, children, housing, water, and environment.
