| LABOR FORCE
(V104) |
| Labor force by place of residence. Estimates represent the sum of the average annual employed (V105) and unemployed (V106) persons by place of residence. "Place of residence" estimates were developed with data secured from establishments and adjusted to remove the effects of commuting and multiple jobholding. This variable is an annual average of monthly data for the calendar year. 1990, 1991, and 1992 data have been revised and are not comparable to previous years. |

| EMPLOYED (V105) |
| Employment by place of residence. All persons who worked for pay or profit, or worked without pay for 15 hours or more per week in a family farm or business. Includes agricultural employment, nonagricultural pay and salary employment, unpaid family workers, and domestic workers in private households. "Place of residence" estimates were developed with data secured from establishments and adjusted to remove the effects of commuting and multiple jobholding.

| UNEMPLOYED (V106) |
| Unemployment by place of residence. Estimated number of residents who did not work at all during the month but were able, available, and looking for work. Includes all jobless persons looking for work, regardless of whether or not they qualify for unemployment insurance benefits. This variable is an annual average of monthly data for the calendar year. County level data are revised both one and two years after the reference year ends. 1990, 1991, and 1992 data have been revised and are not comparable to previous years. |

| PREGNANCIES (V501) |
| Pregnancies for females, all ages. The total number of the following events during the calendar year to resident women of all ages: live births, fetal deaths of 20 or more weeks gestation, and induced abortions. Still births of less than 20 weeks gestation are not included in this count. These figures are generated by adding data from birth certificates, fetal death certificates, and induced abortion reports from abortion providers. The sum of the counties does not always equal data for the state since the state includes persons whose county of residence is unknown. |

| PREGNANCY RATE (N/A) |
| Pregnancy rates are created by dividing pregnancies by female population ages 15-44 and multiplying by 1000. This yields pregnancy rate per 1000 women of childbearing age. |

The total number of the following events during the calendar year to resident women ages 15-19: live births, fetal deaths of 20 or more weeks gestation, and induced abortions. Still births of less than 20 weeks gestation are not included in this count. These figures are generated by adding data from birth certificates, fetal death certificates, and induced abortion reports from abortion providers. The sum of the counties does not always equal data for the state since the state includes persons whose county of residence is unknown. |

| HOSPDISCH
(V512) |
| General Hospital Discharges. Discharges of residents of the county in all short-stay, acute care general hospitals in the state during the federal fiscal year. Excluded are federal and state hospitals, with the exception of one state facility which is included, N.C. Memorial Hospitals in Orange County. Normal ("well") newborn babies are excluded. Counties which border other states reflect under-reporting of discharges since only discharges to residents of the county from hospitals in North Carolina are counted. Counties affected are mainly Alleghany, Camden, Caswell, Cherokee, Clay, Columbus, Currituck, Dare, Gates, Hertford, Pasquotank, and Perquimans. Data for the state do not equal the sum of counties since statewide discharges include N.C. residents whose county is unknown. |

Services.
See HOSPBEDGEN for beds included in short-stay,
acute care, and general hospitals. |
| HOSPADMITS (N/A) |
| General Hospital Admissions. Hospital admissions
at all short-stay, acute care general hospitals in the state
during the calendar year. Excluded are federal and state hospitals,
with the exception of one state facility which is included,
UNC Hospitals in Orange County. Data for the state are equal
to the sum of the facilities in each county. |

See HOSPBEDGEN for beds included in short-stay, acute care,
and general hospitals. |
| LONGTERMCARE (V513) |
| Nursing facility beds. This count includes beds licensed as nursing facility beds, meaning those offering a level of care less than that offered in an acute care hospital, but providing licensed nursing coverage 24 hours a day, seven days a week. In addition to the beds, licensed long-term nursing care (extended nursing care) beds in non-federal, non-state general hospitals are included. Data for each county represent the sum of the beds in the facilities located in that county. Data for the state reflect the sum of licensed beds in the counties. Long-term nursing care beds in both nursing facilities and hospitals are licensed annually for the calendar year. |

| BIRTHLOWWT (V523) |
| Low-weight births under 2500 grams. Newborns weighing under 2500 grams (5 pounds, 8 ounces) at birth, regardless of length of gestation, as reported on the birth certificate for the calendar year, to mothers who are residents. Low-weight births are at increased risk of infant death and illness. The term premature is used in a number of publications. |

| HOSPBEDGEN (V524) |
| Beds in general hospitals. Defined as "beds in use" in hospitals, which are designated for short-stay use as licensed at the end of the third calendar quarter of the year. Included are beds for general medical or surgical use, beds which are for general psychiatric disorders, rehabilitation beds, eye-ear-nose-and-throat beds and pulmonary disease beds. Excluded are beds in all federal hospitals and state hospitals. An exception is the inclusion of beds in one state facility, N.C. Memorial Hospitals in Orange County. Data for each county represent the sum of the beds in the general hospitals located in that county. Data for the state reflect the sum of beds in the counties. |

| MEDICAID (V710) |
| Unduplicated count of Medicaid eligibles. An eligible is defined as a person who receives a Medicaid ID card authorizing Medicaid coverage for any portion of the state fiscal year. Eligibles are unduplicated with respect to the state for the fiscal year. An eligible is counted only in the last county of residence |

| PERSINC (V3001) |
| Total personal income by place of residence (000s). The income received by, or on behalf of, all the residents of the area. Includes income received by persons from all sources - from participation in production, from transfer payments, from government and business, and from government interest (which is treated like a transfer payment). Personal income is the sum of wage and salary disbursements, other labor income, proprietors' income with inventory valuation and capital consumption adjustments, rental income of persons with capital consumption adjustment, personal dividend income, personal interest income, and transfer payments, less personal contributions for social insurance. For counting income, persons are defined as individuals, nonprofit institutions, private non-insured welfare funds, and private trust funds. The last three are referred to as "quasi-individuals." Proprietors' income is treated in its entirety as received by individuals. Life insurance carriers and private non-insured pension funds are not counted as persons, but their saving is credited to persons. Personal income is entirely different from money income, which is a measure of income used by Census and CPS. |

| BEAPOP (V3004) |
| Population estimate by place of residence (BEA denominator). BEA uses the Bureau of the Census county population totals as of July 1. Population is measured at midyear, whereas income is measured as a flow over the year. The state population figure used by BEA will agree with the Bureau of the Census' county estimates but may not be the most current state level figure released by the Census Bureau. These population figures should be used only with BEA income figures to calculate per capita estimates. |
5, 8 |
| PERCAPINC (V3005) |
| Per capita income by place of residence ($). The total personal income of residents of an area divided by the resident population of the area. See BEAPOP and PERSINC. Per capita personal income serves as an indicator of the quality of consumer markets and of the economic well-being of the residents of an area. It should be used with caution for several reasons: (1) An unusually high or low per capita income may be the temporary result of unusual conditions such as a bumper crop, a major construction project, or a catastrophe. In some cases, a high per capita income is not representative of the standard of living in an area. Conversely, a county with a large institutional population may show an unusually low per capita income. (2) Population is measured at mid-year and income is measured as a flow over the year, so a significant change in the population during the year could cause a distortion in the per capita figures. (3) Farm proprietors' income reflects return from current production; it does not measure current cash flows. Sales out of inventories, though included in current gross farm income, are excluded from net farm income because they represent income from a previous year's production. Additions to inventories are included in net farm income at current market prices. (4) In counties that are characterized by small population and almost total dependence upon farming, the per capita income will react more sharply to the vagaries in weather, world market demand, and changing government policies related to agriculture than in counties where the sources of income are more diversified. (5) Substantial differences between BEA estimates of per capita income and Census Bureau estimates are due to differences in definition of income, collection mode, and method of computation. The BEA data are derived primarily from administrative records, while the census data are self reports of individuals. This variable is derived from variables 3001 and 3004 as 100*(V3001)/(V3004). |

| POPULATION (Census/
Estimate/ Projection) (V5001) |
| Depending on the year, this is the corrected census count (April 1, 1970, 1980, or 1990, or the estimate or projection from the State Demographer (April 1, 2000, 2010, July 1, other years). All years subsequent are projected. A projection differs from an estimate in that it relies on certain assumptions about long term trends in data which are not yet available, while an estimate is always based on data from predictor variables which are available for the estimate year. See variables 401-424 for age/race/sex breakdown of the same data for counties (available through the "Population by age/race/sex" topic report option on the main menu of the LINC system). The sum of variables 401-424 for 1990 will not equal variable 5001 for the counties of Buncombe, Cleveland, Durham, Mecklenburg, Pitt, and Robeson because corrections were released after the 1990 data were adjusted. Several municipalities, counties, and the state had corrections to the 1990 population from the Census Bureau. |

| MSA93 (V5015) |
| Metropolitan Statistical Area (1993 definition). A 2 digit number representing the metropolitan statistical area (MSA) to which a given geographic area belongs. MSAs are multi-county regions determined by the federal government based on population and commuting data from the census. MSA 93 represents the 1993 revision, based on the 1990 Census. Since only North Carolina data are available in LINC, any MSA which includes counties outside N.C. is not completely covered in LINC, but instead, the N.C. counties in that MSA are used, and 'N.C. Only' is placed on the end of the MSA name to denote this fact. The non-metropolitan counties (not in any MSA) are grouped together as though they were an additional MSA, Non-metropolitan counties. North Carolina MSA designations have remained constant from 1993 through 1996.
