Which topics have been included in every u. S. Census since the first census in 1790?

The Topic is "Age and Sex"

Explanation:

Since the first census of United States in 1790, the topic that has been included in every United States census is Age and Sex.

In 1790, under the President George Washington, the first United States census was conducted and the population was categorized under different topics, which includes:

1. Free white males of 16years and above

2. Free white males under 16years

3. Free white females

And from there, till the last census conducted in the United States, Age and Sex is a topic that still features in the categories of census.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
