| CBSA (MSA) Code | CBSA stands for Core Based Statistical Area. These are also refered to in the vernacular as MSA codes. The CBSA/MSA is a statistical geographic entity consisting of the county or counties associated with at least one core (urbanized area or urban cluster) of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties containing the core. |

Code which represents combinatins of 2 or more CBSA/MSAs. A combined statistical area represents a geographic entity consisting of two or more adjacent Core Based Statistical Areas (CBSAs) with employment interchange measures of at least 15. Pairs of CBSAs with employment interchange measures of at least 25 combine automatically. Pairs of CBSAs with employment interchange measures of at least 15, but less than 25, may combine if local opinion in both areas favors combination. |
|
| Division Code | A subdivision of a CBSA. A city or town or group of cities and towns within a CBSA that contains a core with a population of at least 2.5 million. A Division consists of a main city or town that represents an employment center, plus adjacent cities and towns associated with the main city or town, or with other cities and towns that are in turn associated with the main city or town, through commuting ties. | |

About our zip code data
We are zip code data specialists licensed to sell zip code data by the USPS. We update every record in our zip code databases monthly. You will always receive the latest and most up-to-date zip code data - guaranteed. Every file is hand edited to create the most accurate zip code data available.
We’ve built our 5 digit zip code database from data we receive under license from the United States Postal Service. Just like the postal service, we start from the bottom up with detailed, house level Zip+4 data. The zip code datasets we receive from the postal service contain over 80 million rows of data. As our IT guy said, to paraphrase the immortal words of Roy Scheider as Brody in Jaws, "I think you'll need a bigger computer!"
Because of the detailed nature of the USPS zip code data, we have to conduct an exhaustive analysis of the data to get it into a format which is actually usable for everyone who is not a mailman. (In layman's terms, we "crunch" the database.) This produces a set of files which are actually manageable and extract the most useful data elements you would want to use from zip code data to link to your datasets or use in your applications.
And because all of this changes so frequently, we do all our analysis each month to ensure that we are delivering the best quality data in the easiest to use format straight to you.
