Glossary and Definitions ...
- Area Code Overlay
- An Overlay refers to the situation in which two (or more) area codes (eg- 403, 587) serve the same geographic area. In the case of Airdrie, area code (587) is the Overlay for area code (403).
The Overlay is necessary when the geographic area requires (or planners expect to need) more phone numbers than can be provided by a single area code.
When an Overlay is present, 10-digit dialing becomes necessary even for local calls. There are different types of Overlays, with each having its own characteristics and dialing requirements.
If you would like to learn more about Overlays, we suggest the Wikipedia entry for Overlays.
- Canadian Postal Code (FSA & LDU)
- The Canadian Postal Code is a 6-character alpha-numeric code (a mixture of the alphabet and numbers) that is used to improve the efficiency of mail sorting and delivery.
The first three characters are called the 'Forward Sortation Area' (or the 'FSA') and indicates a geographical area within Canada. The first and last characters are 'A' through 'Z' and the middle character is always numeric ('0' through '9').
We know of 2 FSA's for Airdrie: 'T4A' and 'T4B'
In an urban area (such as Airdrie), the LDU can indicate a city block, a single building, a complex of buildings or a high-volume mail receiver (such as a payment processor). Since there are so many possibile LDUs, we only show the 'FSA'.
- A portmanteau is the forming of a linguistic combination or contraction by taking two (or more) words, their sound and the meaning of those words to create a new word. For example, smoke and fog becomes smog. An explanation of Airdrie can be found under Toponymy (see below).
- Quinquennial Census
- The Statistics Canada (StatCan) Census is conducted every 5 years with the purpose of counting the people living in Canada. This is known as a 'Quinquennial' Census. The process of taking a Census is called an 'Enumeration'.
The purpose of the Census is to provide information about the demographic and social characteristics of the people of Canada. The results of the Census goes to the federal, provincal, territorial and local governments to support their planning and administrative activities.
The most recent StatCan census was conducted in 2011. The next Quinquennial Census will be conducted in 2016.
By comparison, the United Status Census is conducted once every 10 years and is called a 'Decennial' Census.
