1790 was the first year the United States started to collect "social statistics" information in the form of a census. Since then every decade had produced another census. Each census has improved, adding information that makes it easier to trace your family heritage.

When tracing your ancestors, The United States census can help you discover facts about your ancestors and fill in missing event information, helping to build your family tree. Among the information you can discover: birth dates, birth places, place of residence, occupations, income, immigration years, naturalization status, and more. Another benefit of using the census record is finding family members, giving the genealogist the ability to add missing ancestors, such as children and grandparents.

Understanding Population Schedules for Genealogy Research
Census records are available as Population Schedules. There are also Special Census Schedules that included: slave schedules, state records, agricultural schedules, mortality schedules, manufactures, social statistics, defective classes, and others are available. The state and mortality census records just might help you with tracing your ancestors. Mortality schedules were recorded 1860, 1870, and 1880.

Census takers were directed to secure additional information for persons dying with the 12 months preceding the census taking. For each person, the following information is listed: name, age, sex, marital status if married or widowed, state or country of birth, month of death, occupation, cause of death, and the length of the final illness. These schedules may be the only record of death for some individuals, as many states did not require recording of deaths until the late nineteenth century. In addition, gravestones or cemetery records may be nonexistent.

Tips for Locating Ancestors in Census Records
Census records can help you to pinpoint when someone was born by noting the date of the census and the person's age. When you find them in more than one census, you might find that their age changed from one census record to the next, giving a clue as to when they were born within a couple of months. You can then update your information for that ancestor and use a tighter time frame for their birth. Rather than an approximate year, it might now be an approximate time frame within a couple of months.

When tracing information about your ancestor, remember to look for them using different spellings. Many Census takers often wrote the name the best they could with the way it sounded. And people, who have indexed online databases, have erroneously made mistakes in recording names and information too. The mistakes can be either by transcribing the common handwritten letter or by mistyping the record. If you can't find what you are looking for, search using abbreviations, variations, phonetic spellings, nicknames, initials, or substitute letters that are commonly mistaken for other letters.

If you are looking at copies of microfilms, don't overlook the other people on the same page or the page before or after your ancestor. Often relatives lived in the same household, or within houses from each other.

Avoid Common Family History Research Mistakes
When tracing your ancestors, remember there could be several families with the same name living in the same area. Verify the information belongs to your ancestor before you record the source and its details. Using several documents will help you to verify the information you have is correct. Using our Progress Rating Chart can help you with what information you need to find to complete your family tree.

Consider all reasonable matches when performing searches. Don't assume the first "close" match is the right person or family. Before 1850, people were not listed by name. Don't assume the oldest male in a census record is necessarily the head of household or that everyone is a family member. The family could have raised children other than their own. Listing more children than expected in a household could also indicate a prior marriage.

Missing family members, or a family structure vastly different from what you expected, could be a clue you found the wrong household. Make clear notes in your records as to why you think the information you found fits or does not seem to be your ancestors. Keeping good records will help you stay focused and on track for future searches.
