Classifications and concordances

Classifications Available from Definitions, data sources

and methods Outline the hierarchical structure of non-

numeric concepts Indicate what is included & excluded at each

level of the classification Updated to accommodate new goods,

services, concepts, definitions• Eg NAICS 1997, NAICS 2002, NAICS 2007

Classifications and concordances (cont’d)

Concordances Cross-walk between classifications, ie

outline which categories in one classification are the same as/different from which categories in another classification

Especially important when comparing categories over time

Getting access Levels of access Access to the DSP collection What’s not in the DSP collection

Levels of access Who has access to what, where,

when, and at what cost? One view is Chuck Humphrey’s

continuum of access approach, outlined at:

http://www.statcan.ca/english/Dli/continuumofaccess.htm

http://www.statcan.ca/english/Dli/continuumofaccess.htmFree,

UnrestrictedFor Fee, Restricted

Continuum of Access http://www.statcan.ca/english/Dli/continuumofaccess.htm

Chuck Humphrey, U of Alberta Data Library

Levels of access for Census 2001

Level 1: 'public good access‘ on the STC web site available to the entire general public

Level 2: "public good - expanded access“ more detailed data (eg lower geography) available to DLI, DSP, provincial focal points,

funding federal departments IP address controlled

Levels of access for Census 2001 (cont’d)

Level 2+: DLI (via DLI ftp site) geography to DA and FSA levels includes spatial data products & geographic

reference files (eg Postal code conversion file) selected semi-custom products (eg Travel to

work files) and public use microdata files Level 3:

has the most detail (geography and characteristics)

for internal STC employees only

What’s not on the DSP web site Many statistical (non-pdf) products:

eg Annual demographic statistics Excel files ESAS, Employment dynamics, Small area data,

Canadian Centre for Justice Statistics files,etc. Gradually moving to free STC web access,

eg Health indicators database Human activity and the environment Health regions cd-rom

Public use microdata files Semi-custom and custom products

Some things we learned this year

CPI: index year versus basket Census profiles: community profiles,

electronic profiles, versus E-stat profiles Profile of health regions (2001 census)

CPI index year versus basket

Baskets About 600 goods & services priced each

month (incl. GST & PST) Weights assigned to reflect importance

of the items in the basket 1% change in price of milk affects index

more than 5% change in price of tea Updated about every 4 years

1992 basket was first to include GST 2001 basket contains ‘Internet service

charges’, previous baskets didn’t

Base (index) yearsThe CPI reflects prices relative to a base year

Dec. 2002 price of Internet access (Ontario)=100.0

Dec. 2005 price of Internet access (Ontario) =97.0

Ie price fell ((97.0-100.0/100.0)*100)=3% between the end of 2002 and end of 2005

We don’t know what the prices were at those to times, just that the price came down

Average prices of foods, gasoline and tobacco in current basket in 62-001-XIB

How do I convert an index to another

base year? Compute a ratio = [new index at

time1]/[old index at time1]. Eg new index has base year 1995=100; the old

index has base year 1985=100 the index value for year 1995 (1985=100) was

127.5; the value for year 1995 (1995=100) is 100

the ratio is (100/127.5)=.7843 Multiply values on the old index by .7843

to convert them to the new base year (1995=100).

Conversion factor:

(100/127.5)=0.7843

New series=(old series x conversion factor)

Census profiles …many flavours

There are 5 main products you should be aware of (2001 census): Community profiles Electronic profiles Census profiles on the E-stat web site Profile of health regions Topic-based tabulations – for additional

breakdowns (in addition to gender)

Community profiles (2001) available to the public (on STC web site) main characteristics only (about 190

characteristics per geographic area) many are percentages (rather than counts) breakdowns by geography only geography includes provinces/territories,

counties (CD), municipalities (CSD), CMAs and health regions

comparison with province level statistics is default

output: print, or comma-separated file (with no extension)

Electronic profiles Available to the public: STC web page & DSP About 1700 characteristics per geographic

area Many characteristics broken down by gender Wide range of available geographies, from

province to census tract. (DA and FSA are DLI only)

Comparison with other geographies ‘manually’ Output: comma-separated file, text file, or

Beyond 20/20

Profiles on E-stat available to the public under DSP includes all census profile characteristics

(1700+) geography by county (CD), municipality (CSD),

CMA and census tract only select by postal code capability (census-tract

level profiles) widest range of output products, including

interactive mapping includes Census of Agriculture products

Profile of health regions (2001)

Not linked to 2001 census profiles web pages Access from Health regions web page About 1250 census characteristics Beyond 20/20 format
