Citizens of the United States are guaranteed certain rights. They are also expected to carry out certain duties and accept important responsibilities. By obeying the law, paying taxes, serving in the armed forces and in court, and attending school, citizens contribute to the growth and the strength of our nation. Many of the responsibilities of citizenship are voluntary rather than legal duties. Staying informed about issues, making your opinion heard, and voting are all important to the principles of democracy. Citizens should also practice tolerance and respect the rights of others. Government cannot meet all of the needs of its citizens. That is why volunteerism is so important. Every year more than half of all Americans engage in volunteer work to help make their communities better places to live.
