NOTES

1. Modified from: Bureau of the Census, "Neighborhood Characteristic s Record", Public Use Samples of Basic Records From the 1970 Census: Description and Technical Documentation, Washington, D.C.: Department of Commerce, 1972, pp. 85-89.

2. The "Spanish heritage" population referred to here is differently defined in three areas of the country: in New York, New Jersey, and Pennsyvania, persons of Puerto Rican birth parentage; in Texas, Colorado, New Mexico, Arizona, and California, persons of Spanish language and/or Spanish surname; in all other States, persons of Spanish language.

3. The index of income concentration ranges from .01 to .99. As the index approaches 1.0, the greater is the inequality of the income distribution. A code of 00 indicates the index was suppressed due to unreliability

4. Poverty status is not determined for inmates of institutions, armed forces living in military barracks, college students living in dormitories, or for unrelated individuals less than 14 years old.

5. Units where the primary individual or family income is zero or negative and units for which no cash rent is paid are excluded from tabulation of the rent-income ratio.
