Birth date
An individual's birth date can usually be found on any of the documents listed below. If you have the minimum information required to find one of these documents, select the name of that document. The items in the list are ordered from most to least important. If you do not have the minimum information required, read the paragraph below this list.
Finding a birth date with vital records
An individual's birth certificate is the best place to look for a birth date, because it is a primary source for that information. Birth certificates are available from either the county or the state where the birth took place, depending on the year of the birth. In addition, you usually can find an individual's birth date on other vital records, such as marriage, death, and divorce certificates. These are also available from either the county or the state where the event took place. To get the address where you must write to obtain any of these vital records, see the topic Resources by state.
When looking for marriage records, many people use computerized marriage records indexes to help them find the record that they need. Some libraries have computerized marriage records indexes.
Also, make sure to check photo albums, scrapbooks, diaries, and family Bibles at home. See the topic Finding information at home for more information. Also check for local histories. See the topic Finding previous research.
Finding the minimum amount of information for vital records
To find an individual's birth date on a vital record, such as a birth, death, divorce, or marriage certificate, you must at least know the individual's full name, the approximate year of the event, and the state or county of the event, depending on when the event took place. If you do not have the minimum information to find a birth certificate or other vital record, you can either:

Even if you don't have the minimum information required to find the original records, you're not completely out of luck. Indexes to vital records have been made for some states and counties. These indexes provide you with the information you need to access the original record. Check with libraries and genealogy societies in the area -- they may know if any indexes exist for the records that you need.
Finding a birth date with church records
You can usually find an individual's birth date or age on church marriage, baptism, and christening records. When you have an age, you can estimate the birth date.
The books listed below can help you locate your ancestors' church records by telling you who currently has the records belonging to your ancestors" church. You can find these books in a public or genealogical library. Depending on the book that you use, you can look up either the name of your ancestors' church or the name of the clergyman and find out who currently has the records belonging to your ancestors' church. Of course, if you live close to your ancestors' church, you should go directly to the church and ask the staff for assistance in locating the records that you need.

Once you locate the records that belong to your ancestors' church, the current custodian of the records should be able to direct you in your search for the marriage, baptism, or christening record that you need. Baptismal records do not always have a birth date on them, but just the date of baptism. Often the delay between the birth date and the baptism was only a few days, but you should find out what was customary for that era and denomination. Then, you will be able to estimate the birth date.
Another good place to look for both American and foreign church records is among the microfilm records at the Family History Library of the Church of Jesus Christ of Latter-day Saints. Their church records are organized first by state, then county, and then town. Unless the town that you are searching for had very few churches, knowing a denomination will make your search easier.
Finding the minimum information for church records
To find an individual's birth date in church marriage, baptism, or christening records, you must at least know the individual's name, and either the name of the church where the ceremony was performed or the name of the clergyman that appears on the certificate.

If you can find out the denomination of your ancestor's religion, you can try contacting all of the churches of that denomination in the area where you believe your ancestor lived. If they have records from the corresponding time period, they should be able to tell you whether or not your ancestor was a church member. If their records do not go back far enough, they may be able to tell you if any other churches of that denomination existed in the area at the time and where their records may be.
Finding a birth date with newspapers
A birth announcement can give you an exact birth date when you only have an approximate date, and obituaries normally list an individual's birth date, or at least an approximate age. The most interesting part about looking up obituaries and birth announcements is that you may also find a picture of the individual.
The directories listed below will help you find the current owners of old newspapers from the time and place when the birth announcement or obituary was published. If the individual spoke a foreign language, check to see if there was a newspaper in that language, too. Once you have located the current owners, you can request to search the appropriate copies. The current owners should be able to direct you in your search.

Finding birth dates with Bible records
Family Bibles often include family members' birth dates. Make sure that you have asked your family members whether or not they are aware of any old Bibles that are still in the family. When you find information in actual Bibles, check the publication date of the Bible. If the Bible was printed in, for example, 1871, but a birth is recorded for 1851, you know that the date of that particular birth was not written down at the time of the birth, but was written down several years later. Dates recorded after the fact are less likely to be accurate.
When you cannot find family Bibles among your own family members, check with genealogical societies in the area where the family lived. They may have or be aware of the location of local Bible records. When you are searching for Bible records, be sure to look under both the maiden name and married name.
Next, search through the transcribed Bible records belonging to the Daughters of the American Revolution (DAR). These transcribed Bible records are available at the DAR library in Washington, D.C., local DAR chapters, and on microfilm through the Family History Centers of the Church of Jesus Christ of Latter-day Saints. See the topic Libraries with a National Focus, Including LDS for information about these two libraries.
Finding the minimum information for Bible records
To find an individual's birth date in Bible records that are no longer in the family's possession, you must at least know the individual's maiden name or full married name, as well as the state and county in which the individual lived.

Finding a birth date with military records
Veteran's Benefit Records may show an individual's birth date if either the individual or the individual's spouse served in the military. To get the address where you must write to obtain a military record, go to the topic Researching through military records, and see the category "Veterans' Records."
Ancestry also has millions of digitiized and scanned military records, documents and indexes .
Finding the minimum information for military records
To find an individual's birth date in a military pension record, you must at least know the veteran's name, the branch of service, such as Army, Navy, or Marine Corps, the state from which the veteran entered the service, and the war in which the veteran served. If the period of service was after 1916, you must also know entry and release dates, military ID number, Social Security number, whether an officer or enlisted, and date of birth. If you do not have the minimum information to find a military record, you can either:

If you aren't sure of the military branch or of the approximate time when the veteran served, look for military memorabilia an photos taken in uniform. These items can give you the information you need.
If the individual was a veteran who served and was killed in the Korean or Vietnam War, you may be able to find a birth date through the death records in the Military Index on the FamilySearch computer at your local Family History Center of the Church of Jesus Christ of Latter-day Saints. The Family History Library has all other wars indexed on microfiche. You only need to know the war and the veteran's name. Local community and genealogy libraries may also have war indexes. Contact individual libraries for their holdings.
Finding a birth date with census records
Beginning in 1850, the census recorded the age of each individual in the family at their last birthday. To find out if your ancestor appears in an 1850 or later census, it's easiest to search databases online. Ancestry's census collections have both digitized and scanned copies of every US Census. Even if you don't find the exact name that you need in the index, it is worth it to start looking at all records for families with that surname in the state, as long as the surname isn't too common. For example, if you are looking for Roberto Zubilaga, but only find John Zubilaga and Gianni Zubilaga in the index, look at those records. Using this method, you may come across the family that you are looking for.
At many libraries you can find bound or digital indexes for pre-1880 censuses. Indexes are organized by state and list individuals in alphabetical order by surname, so you don't need to know the county. Different indexes contain different information that will help you find the census record. Some just give you the county that the person lived in; others tell you more. You can find bound indexes at the National Archives and the National Archives regional centers , the Family History Library of the Church of Jesus Christ of Latter-day Saints and branch Family History Centers , and many other libraries. Different locations have different indexes, so check more than one library if you don't find the index that you need. In addition, Soundex indexes are available, with some exceptions, for the years 1880 to 1920. For information about Soundex, see the topic Soundex: what it is and how to use it.
Once you locate your ancestor's name in an index, you will want to look at microfilm copies of the original census records. The original records will help you find the information you need and verify that you have found your ancestor, and not just someone with the same name. Pre-1940 census records are available at the National Archives and National Archives regional centers. Also check with your local public and genealogy libraries, because they may have census records or be part of an interlibrary loan system. In addition, your local Family History Center of the Church of Jesus Christ of Latter-day Saints may either have census records or be able to get copies of them for you.
Access to post-1940 census records is restricted to immediate relatives and descendants. If the individual whose records you are searching for is still living, you must have their written permission to obtain a copy of the record. If the individual is deceased, you must have a certified death certificate. Write to: Bureau of the Census, P.O. Box 1545, Jeffersonville, IN 47131. They will send you a form that you must fill out and return with a fee.
You may also want to check the information contained in state and local censuses. Not all states and localities took their own censuses and the contents vary from state to state. However, sometimes the information is quite valuable. Ancestry has a selection of state census records online , and you can also contact libraries, state archives, and genealogy societies in the area where your ancestors lived. They should be able to tell you if any exist and where you might find them. The Family History Library of the Church of Jesus Christ of Latter-day Saints is another possible source.
Finding the minimum information for census records
To find an individual's birth date in census records, you must at least know the individual's name, the state, and the county in which the individual lived when the census was taken. If you are using census records for 1870 or earlier, you can probably use an index that only requires the state and surname.
Get help finding some of the minimum information by selecting one of the following items:
You can approximate a couple's marriage date if you know the birth date of the oldest child. Pregnancies often happened soon after a couple's marriage, so you can estimate the marriage date to be 1-2 years before the birth of the first child. This will at least give you a target range of years in which to search for the records.
Finding a birth date with the Social Security Death Index
With the Social Security Death Index, you can get information regarding an individual's birth date, death date, Social Security number, state/county code of residence, last residence zip code, and the zip code where the death benefit lump sum payment was sent.
In addition, with a name, the Social Security number that you get from the Social Security Death Index, and $7, you can obtain a copy of the individual's original application for a Social Security card. This often contains much information of genealogical interest. Write to: Freedom of Information Officer, 4-H-8 Annex Bldg., 6401 Security Blvd., Baltimore, MD 21235.
You can search the SSDI on Ancestry if your ancestors are listed in the Social Security Death Index without even leaving your computer!
You also can access the Social Security Death Index in several other places. For example, many larger libraries have the Social Security Death Index databases. In addition, you can use the index through the FamilySearch computer. This a computer system at the Family History Library of the Church of Jesus Christ of Latter-day Saints. The Social Security Death Index is also available at the National Archives and some of the regional branches of the National Archives. Contact your local branch of the National Archives to find out whether or not they have the Social Security Death Index before you make a special trip. For addresses and phone numbers of the National Archives and each of the regional branches, see the topic National Archives.
Finding the minimum information for the Social Security Death Index
To find an individual's birth date in the Social Security Death Index, you only need to know the individual's name.

Finding a birth date with the International Genealogical Index
The International Genealogical Index (IGI) is an index created by which documents records of deceased persons from around the world. The Parish and Vital Records List, which is published by the Family History Library of the Church of Jesus Christ of Latter-day Saints, shows which records have been extracted and listed in the International Genealogical Index for each geographical area and time period. It also shows which records are currently being extracted. Most of the names in the International Genealogical Index come from records dating from the early 16th century to the late 19th century. The index does not include every person from any given country, nor the names of all persons from the records indexed.
The International Genealogical Index was created and is maintained by the Family History Library of the Church of Jesus Christ of Latter-day Saints. You can access it through the Family History Library, and it may also be available at some major genealogical societies and libraries.
It should be noted that the extracts from the original records that are recorded in the International Genealogical Index are not always accurate. Many agree that there is wide variation in the reliability of the records found in the International Genealogical Index. For these reasons, the International Genealogical Index is recommended as an excellent source of information, provided that you verify your information against original documents.
