Most Jews identify as Zionists, with estimates of 63–80% in the U.S. and UK, and nearly 99.9% in Israel, based on surveys. Zionism supports a Jewish homeland in Israel, but views vary by region and age. In the U.S., 76% of Reform Jews and 70–80% overall lean Zionist, though 42% of young Jews are unsure of the term. In the UK, 63–80% identify as Zionist, with a slight decline. Israel’s Jewish population strongly aligns with Zionism due to its national identity. Attitudes are shifting, especially among younger, progressive Jews.
