1
00:00:01.400 --> 00:00:04.272
This episode focuses on bulk and microdata access.

2
00:00:04.272 --> 00:00:11.797
Census data becomes useful when the population, measure, geography, and time period are stated before anyone searches for a number.

3
00:00:11.797 --> 00:00:15.691
Summary files support bulk access to published aggregate estimates.

4
00:00:15.691 --> 00:00:23.654
They preserve table structure and geography but require careful use of lookup files, sequence layouts, annotations, and margins of error.

5
00:00:23.654 --> 00:00:30.787
Public Use Microdata Sample files contain disclosure-protected person and housing-unit records for custom analysis.

6
00:00:30.787 --> 00:00:35.750
They are samples, require weights, and identify only selected large geographies.

7
00:00:35.750 --> 00:00:40.092
Public Use Microdata Areas are the most detailed geography identified.

8
00:00:40.092 --> 00:00:45.105
Never infer that a PUMS record represents a named person or a specific neighborhood.

9
00:00:45.105 --> 00:00:50.417
Follow API and privacy terms, use replicate weights where required, and document recodes.

10
00:00:50.417 --> 00:00:55.550
A custom estimate needs the same uncertainty and universe checks as a published table.

11
00:00:55.550 --> 00:00:57.012
Torrance application segment.

12
00:00:57.012 --> 00:01:00.593
This local application is separate from the Census Academy instruction.

13
00:01:00.593 --> 00:01:11.990
The cited City of Torrance primary source is General Plan, published at https://www.torranceca.gov/Government/Departments-Offices/Departments-Offices/Community-Development/Planning-Division/Comprehensive-Planning/General-Plan.

14
00:01:11.990 --> 00:01:18.445
For a local analysis, use summary tables for Torrance-specific geography and do not label PUMA microdata as city-level evidence.

15
00:01:18.445 --> 00:01:25.555
Do not present City policy or administrative records as Census Bureau findings, and do not present a federal estimate as adopted City policy.

16
00:01:25.555 --> 00:01:35.396
Keep a reproducibility packet containing the question, source URLs, exact vintage, table or query, geography codes, raw result, calculations, and uncertainty note.

17
00:01:35.396 --> 00:01:38.596
This narration is an original synthesis of cited U.S.

18
00:01:38.596 --> 00:01:43.306
Census Bureau government works and separately cited City of Torrance material.

19
00:01:43.306 --> 00:01:47.532
Third-party videos, software, graphics, and linked works are excluded.

20
00:01:47.532 --> 00:01:53.449

21
00:01:53.449 --> 00:01:57.736
