Social, Economic, Environmental, Demographic Information System (SEEDIS)

The "Social, Economic, Environmental, Demographic Information System (SEEDIS)"
is a research and development project at the Lawrence Berkeley Laboratory,
supported by the U.S. Department of Energy (USDOE), U.S. Department of Labor
(USDOL), and others. It was initiated in 1972 by USDOL as a demonstration
project to link data from multiple sources. Since that time, the project has
been expanded. SEEDIS's main purpose is to provide accurate, and timely
information for policy formulation, implementation and management. The SEEDIS
Project addresses these information needs by providing a unified framework for
data management, information retrieval, statistical analysis, and graphic
display of data from a collection of databases for various geographic levels
and time periods, drawn from the U.S. Census Bureau, the U.S. Environmental
Protection Agency (USEPA) and the Department of Health and Human Services.

SEEDIS contains information on Census, energy, environment, geography, health,
population characteristics, and socioeconomic status. SEEDIS allows the user to
produce graphical and map presentations of analyses of combinations of these
data for a variety of geographic levels and scope.

SEEDIS' census information relates to population size by major racial and
ethnic groupings for 1970 and 1980. These data are variously available at the
national, state, county, city and census tract level.

SEEDIS' energy information relates to electrical generating capacity for 1960
through 1995. These data are available at the national, county, and
standardized metropolitan statistical area (SMSA) level. The data system also
contains 1970 residential housing data, and heating energy requirements in
1970, and biomass resources for 1976 and 2025 at the county geographic level.

SEEDIS' environmental information relates to air quality measurements for
criteria pollutants. The data are available for 1974 through 1976 at the census
tract level. They are derived from the AIRS data system (formerly SAROAD).
Assessments include total suspended particulates (TSP), sulfur and nitrogen
dioxides, photochemical oxidants, ozone, carbon monoxide, sulfates, and total
and nonmethane hydrocarbons. For each pollutant, county estimates of pollutant
concentration (at the position of the county population centroid) were
calculated as the weighted geometric means of measurements from nearby
stations, including stations in nearby counties. The location of the air
quality monitoring stations is also available from the National Air Monitoring
Stations (NAMS) data system.

SEEDIS' geographic information relates to the centroids of the 1970 household
populations. The data are available for a variety of geographic levels. The
areas, centroids, and boundaries of census tracts and counties are also
included.

SEEDIS' health information relates to age-, sex-, and race-specific total
mortality. The data are available for geographic levels as small as counties
for the years 1969 through 1984. In addition, total annual leukemia mortality
is available. Cancer incidence for 1973 through 1981 from the Surveillance,
Epidemiologic, and End Results (SEER) registers is included for the states that
participate in the program.

SEEDIS' population relates to age-, race-, and sex-specific population counts
(from the 1980 Census) and estimates for the years 1950 to 1987. The data are
available for varying geographic levels. Estimates are available from a variety
of sources.

SEEDIS' economic information relates to labor force, employment by industry,
income, education, fertility. It also contains data on the Census of
Agriculture and many county- and state-specific data.

**社会、经济、环境与人口信息系统（Social, Economic, Environmental, Demographic Information System, SEEDIS）** 是劳伦斯伯克利实验室的研发项目，由美国能源部（U.S. Department of Energy, USDOE）、美国劳工部（U.S. Department of Labor, USDOL）等机构资助。该项目于1972年由美国劳工部发起，作为整合多源数据的示范项目，后续经历了多次扩展。SEEDIS的核心目标是为政策制定、执行与管理提供准确及时的信息支持。SEEDIS项目通过构建统一框架，实现多源数据库的管理、信息检索、统计分析与可视化展示，以此满足上述信息需求。其数据来源涵盖美国人口普查局、美国环境保护署（U.S. Environmental Protection Agency, USEPA）以及美国卫生与公众服务部，覆盖不同地理层级与时间跨度的数据集。

SEEDIS收录了人口普查、能源、环境、地理、卫生、人口特征与社会经济地位相关数据。用户可基于该系统对多维度数据组合开展分析，并生成对应不同地理层级与范围的图表及地图可视化成果。

SEEDIS的人口普查数据涵盖1970年与1980年按主要种族与族群划分的人口规模信息，可分别获取全国、州、县、城市以及普查区块组层级的数据。

SEEDIS的能源数据涵盖1960年至1995年的发电装机容量信息，可获取全国、县以及标准都会统计区（Standardized Metropolitan Statistical Area, SMSA）层级的数据。此外，系统还收录了县级层面的1970年住宅数据、1970年供暖能源需求数据，以及1976年与2025年的生物质资源数据。

SEEDIS的环境数据包含环境空气污染物监测数据，1974年至1976年的普查区块组层级数据源自AIRS系统（前身为SAROAD）。监测指标涵盖总悬浮颗粒物（Total Suspended Particulates, TSP）、二氧化硫、氮氧化物、光化学氧化剂、臭氧、一氧化碳、硫酸盐，以及总烃与非甲烷烃。针对每种污染物，系统以周边监测站（含邻近县域的监测站）的观测值为权重，通过几何平均法计算得到县域人口重心处的污染物浓度估算值。空气质量监测站的点位信息同样可通过国家空气监测站（National Air Monitoring Stations, NAMS）系统获取。

SEEDIS的地理数据包含1970年家庭人口重心信息，覆盖多种地理层级，同时收录了普查区块组与县的面积、重心及边界数据。

SEEDIS的卫生数据包含按年龄、性别与种族划分的全死因死亡率信息，1969年至1984年的数据可获取至县域层级。此外，系统还收录了年度白血病死亡总数数据；参与项目的州的1973年至1981年癌症发病率数据源自监测、流行病学与最终结果（Surveillance, Epidemiology, and End Results, SEER）登记系统。

SEEDIS的人口数据包含按年龄、种族与性别划分的人口数（源自1980年人口普查）以及1950年至1987年的人口估算值，覆盖不同地理层级，估算数据源自多类数据源。

SEEDIS的经济数据涵盖劳动力、行业就业、收入、教育与生育率信息，同时收录了农业普查数据以及大量县域与州级专项数据。
