trigger CopyCountryFromAccountToContact on Account (after update) {
    List<Contact> contactsToUpdate = new List<Contact>();

    for (Account acc : Trigger.new) {
        // Check if the country field has been updated
        if (acc.Country__c != Trigger.oldMap.get(acc.Id).Country__c) {
            // Get all Contacts associated with the updated Account
            List<Contact> contacts = [SELECT Id, Country__c FROM Contact WHERE AccountId = :acc.Id];
            // Update the country field of each Contact
            for (Contact con : contacts) {
                con.Country__c = acc.Country__c;
                contactsToUpdate.add(con);
            }
        }
    }

    // Bulk update the Contacts
    if (!contactsToUpdate.isEmpty()) {
        update contactsToUpdate;
    }
}
Note: In this code, the custom field Country__c is used on both Account and Contact objects. Please replace it with the actual field name if it is different in your org.
