Where did people move after The frontier was fully settled

After the frontier was fully settled, people began to move to urban areas in search of employment opportunities and better living conditions. Many migrated to large cities such as New York, Chicago, and Los Angeles. Others moved to smaller towns and suburbs in search of a quieter and more peaceful lifestyle. Some migrated to new parts of the country that were still developing, such as the West Coast, where there were ample opportunities for land ownership and business ventures. Many people also migrated to industrialized regions, where they could work in factories and industries that were expanding rapidly.
