Pages describing the concepts and tables covered by the Census and American Community Survey.

Age and Sex

How the Census approaches the topics of age and sex.

Blood Lead Level

Data on the number of tests for elevated blood lead level is collected by the Michigan Department of Health and Human Services at the individual level. For this analysis, D3 anonymized the data and aggregated it up to various geographies. Geographies with less than 6 individuals with elevated blood lead levels (EBLLs) are suppressed to preserve anonymity. EBLLs are defined as a blood lead level greater than 4.5 micrograms per deciliter (the unit of measure used to determine lead levels which is micrograms of lead per deciliter of blood). There are two different types of samples, capillary and venous. Capillary testing is done by a pricking the skin of a fingertip or heel capillary. Venous testing is done by drawing blood directly from an arm vein. Some children receive both types of testing, but not all children receive venous testing. Venous is preferred for accuracy and used in the SDC tool as the method of identifying EBLL.

Commute

Commute data from the American Community Survey.

Education

The Michigan Center for Educational Performance and Information (CEPI) coordinated the collection of education data for the State of Michigan. This data includes M-STEP test data, graduation, and drop out statistics. Through this data we report information related to both English Language Arts (ELA) and Math M-STEP testing that takes place during the 3rd grade, and graduation rate information. Data from CEPI is published for both traditional public schools and charter schools. The numbers that we report on the Housing Information Portal from the tables below include both public and charter schools combined. If there are fewer than 10 observations, the information is suppressed for privacy reasons.

Employment

While the ACS is not always the best source for employment data, it provides interesting information for small geographies that other sources do not cover.

Families

Families are an important topic in the ACS and a key framework for considering many kinds of data.

Geography

Geography is fundamental to the Census Bureau's process of tabulating data. Here are the key concepts you need to understand.

Getting Started

The Census is a big subject and there's a lot to learn, but you don't have to learn it all at once. Here's some help knowing the lay of the land.

Housing

The ACS collects a variety of information on housing, providing insights on housing markets and conditions at various geographic levels.

Income

How the Census approaches the topic of income.

Migration

How the Census deals with migration data.

Poverty

Poverty data and how it is used within the ACS.

Public Assistance

Public assistance data from the ACS.

Race and Hispanic Origin

Race is a complex issue, and no less so with Census data. A large proportion of Census tables are broken down by race.

Same-Sex Couples

Although Census does not ask about them directly, there are a number of ways to get at data about same-sex couples using ACS data.

Seniors

In addition to basic Census data about age, there are a small number of Census tables which focus directly on data about older Americans, and on grandparents as caregivers.

Table Codes

While Census Reporter hopes to save you from the details, you may be interested to understand some of the rationale behind American Community Survey table identifiers.

Veterans and Military

Data collected about past and present members of the U.S. Armed Forces.
