INTRODUCTION This document is intended to provide a user-friendly guide that details all of the rules that incoming Revised Natality records are subject to, upon submission to the National Vital Statistics System (NVSS), as part of the Vital Statistics Cooperative Program. This is a living document, and will be updated as rules are modified and introduced. This process is continuous, resulting from the quality control operations performed on the data by the Data Acquisition, Classification and Evaluation Branch (DACEB) in Research Triangle Park, North Carolina. This document may contain information that is different from that which is published in the "Birth Edit Specifications For the 2003 Revision of the U.S. Standard Certificate of Birth". This new document does not serve as a replacement for that one, but rules contained herein supersede any that are explicitly stated in the older document for the purposes of routine feedback from NCHS to Jurisdictions. The rules and calculations in this document may differ from those provided by the Division of Vital Statistics as part of our year-end processing. Rules contained in this document are designed to quickly evaluate impossible or improbable conditions and values, in order to clean up data before the files are closed. Our year-end processing includes imputations and conversions designed to convert invalid, missing, or unknown values into valid values, following proscribed statistical methods. This document uses the term "jurisdiction" to refer to one of the 57 states, cities or US possessions that participate in the VSCP, but there are certain variable names that have traditionally used the word "state", and those are retained in this document. Likewise, references to Counties include county-like entities which may differ from jurisdiction to jurisdiction.

FORMAT The document contains an entry for every variable on the file, accounting for all 1000 bytes required to be submitted for a Revised Natality record to be considered whole, and the entries are provided in sequence, from the beginning of the file to the end. Calculated fields are shown immediately after all components for the calculation have been described.

Position Variable Name Length Date Effective Data Years 61 Date of Birth (Mother)—Day

2 25 Jan 2010 2008 - Forward

Each entry shows the position in which the variable begins, the standard name for the variable, the length of the variable on the file, the date the documented information was first put into production, and the data years in which the information applies to.



Typically, any changes made will go into production on 01 January of a given year, affecting only that data year and future data years, but there may be cases where rules become effective at different times. Any changes posted will indicate precisely when the change will be put into effect, and which data years must follow the modified rules. After each item's header, any of 4 different types of rules may be listed, and more than 1 rule may be listed for any variable.

REJECTION Values failing these rules will result in the record being rejected in its entirety. No additional rule checks are performed on the record. If this is a new record, it will NOT be inserted into the NVSS database, and will be considered MISSING. If this is an update record, any new values contained in the record will NOT be updated in the NVSS database. VALIDATION Validations may either be SIMPLE (affecting only one variable) or COMPOUND (affecting multiple variables). Values that fail SIMPLE validation are not within the acceptable range, and must be changed by the jurisdiction to one of the valid values shown. Values that fail COMPOUND validation may contain components that are individually valid, but their combination is not acceptable. One or more of the values in the failed validation must be changed such that the combination of variables evaluated is valid. Labels are shown for coded values. Some validations may require interim calculations to be made, denoted as CALCULATION. VERIFICATION Verifications may either be SIMPLE (affecting only one variable) or COMPOUND (affecting multiple variables), and are values or combinations of values that have passed VALIDATION, but are considered possible outliers. SIMPLE verifications affect variables that do not have an associated Edit Flag. These values require that the jurisdiction verify the value that has been reported (either at the time the data is collected or via follow-up querying), and either correct the value, or contact the assigned DACEB Vital Statistics Specialist, who will remove the VERIFICATION from future cumulative reports. COMPOUND verifications affect sets of variables that may or may not have an associated Edit Flag. These combinations must be verified or corrected by the jurisdiction. If available, the jurisdiction may set the Edit Flag to the proper value to confirm the verification, or may contact their assigned DACEB Vital Statistics Specialist, who will remove the VERIFICATION from future cumulative reports.



NO EDIT There are no edits performed on these variables. These items are shown for completeness. Sometimes, when jurisdictions request that NCHS returns files to them for their convenience, we may store certain calculated values in these fields.

Some items must be calculated (also denoted by CALCULATION) by applying an algorithm to other provided variables to arrive at a new variable. Pseudo-code is provided for each calculated item. These calculated fields are then subject to Validation and Verification. Typically, the algorithms are written such that calculated fields are not tested if any of the individual components have already failed a rule. For items which we have noticed consistent reporting problems, or have particularly complex rules, additional information or examples may be provided in a section labeled as NOTES. Jurisdictions not reporting certain items or categories must notify their assigned DACEB Vital Statistics Specialist in writing before transmitting their initial files to NCHS. This is necessary so that we may adjust our systems to exclude the appropriate items or categories for the jurisdiction from our Validations. Otherwise, all variables not properly reported will be returned as errors to the jurisdiction for correction.



DATA ELEMENTS



Position Variable Name Length Date Effective Data Years 1 Date of Birth (Infant)—Year

4 25 Jan 2010 2008 - Forward

REJECTION The first two bytes must be 20. The last two bytes must be the same as the 3rd and 4th bytes of the filename submitted by the jurisdiction, representing the last two digits of the data year. NOTES Records in a shipment must all come from the same data (calendar) year, and should reflect the year the event occurred, not the year the event was submitted. If a jurisdiction needs to submit records from a previous year, they must be in their own properly-named shipment. Records from the future are never acceptable. Example: 2016 is the only acceptable value for this variable for all births occurring in a jurisdiction during Calendar Year 2016.



Position Variable Name Length Date Effective Data Years 5 State of Occurrence

2 01 Jan 2014 2014 - Forward

REJECTION The value must be the same as the 1st and 2nd characters of the filename submitted by the jurisdiction, which must be the appropriate code for the submitting jurisdiction, as listed in Instruction Manual Part 8, 2014 version, Chapter 3b State Listing [including YC for New York City]. NOTES Jurisdictions should only submit records issued by their own jurisdiction, and never submit records received from other jurisdictions as part of the Interjurisdictional Exchange program.



Position Variable Name Length Date Effective Data Years 7 Certificate Number

6 25 Jan 2010 2008 - Forward

REJECTION The value must consist of 6 numeric bytes. The value may not be 000000. The value must be unique within the shipment. The value may not exceed, by more than 20%, the value of the reported Final Certificate Number from the current year, or in the absence of that, the value of the Final Certificate Number from the previous closed year, by range. NOTES If more than one record is submitted in a shipment with the same certificate number, all versions of that certificate are rejected. Since we do not know which version of the record is the most current, the jurisdiction must re-submit the record uniquely in a future batch. Jurisdictions often use reserved high ranges of certificate numbers for internal purposes for records that are not sent to NCHS as part of the VSCP. When jurisdictions submit these records by accident, large gaps of MISSING certificates are created, so these extraneous records will no longer be accepted if they fail this rule. Jurisdictions that choose to alter their ranges between data years must notify their assigned DACEB Vital Statistics Specialist in advance, to prevent their records from being rejected. Examples: If Jurisdiction X reported certificates ranging from 000001 to 050000 during the previous year, we would reject any certificate submitted during the current year exceeding a number of 060000 (20% more than 50,000). If Jurisdiction Y reported certificates ranging from 100001 to 120000 and 200001 to 230000 during the previous year, we would reject any certificate submitted during the current year from 124000 (20% more than 20,000) to 200000, as well as any certificate exceeding 236000. (20% above 30,000).

NO EDIT NOTES The Matching Number is intended to be reported on all births. Singleton births should report 000000 as their Matching Number. All births in a multiple set should be given the same unique Matching Number so that they can be linked for analytic purposes. If possible, fetal deaths that occur as part of a multiple set should also be linked with the same unique Matching Number. The Matching Number should not contain the certificate number of another birth from the set, but rather all births and fetal deaths from the same pregnancy should receive the same Matching Number.

NO EDIT NOTES Jurisdictions do NOT submit Receipt Date. It is a system-assigned Year-Month-Day value that is stored with each record and reflects the date the Jurisdiction first filed the record with NCHS. The date is never updated, no matter how many times the record is transmitted to NCHS. The Receipt Date must be on or after the Date of Birth—(Infant). NCHS stores the Receipt Date in these positions if files have to be returned to a jurisdiction for any reason, in YYYYMMDD format.

SIMPLE VERIFICATION Values requiring Verification Less than 0 NOTES NCHS prefers that Certificate Numbers NOT be recycled, because of the potential problems associated with ensuring we have the correct information, but there may be occasions where the practice is necessary. If a record's Event Date is updated because of recycling, and is now beyond the date the record was first received at NCHS, it will be reported back to the Jurisdiction as a VERIFICATION error. Once the state has confirmed that the Certificate Number was recycled, it will be removed from future reports. States may still NOT submit records with Event Dates in the future.
