ACS DEMOGRAPHIC AND HOUSING ESTIMATES HISPANIC OR LATINO AND RACE - DP05 Universe - Total population Survey-Program - American Community Survey 5-year estimates Years - 2020, 2021, 2022 The terms “Hispanic,” “Latino,” and “Spanish” are used interchangeably. Some respondents identify with all three terms while others may identify with only one of these three specific terms. People who identify with the terms “Hispanic,” “Latino,” or “Spanish” are those who classify themselves in one of the specific Hispanic, Latino, or Spanish categories listed on the questionnaire (“Mexican, Mexican Am., or Chicano,” “Puerto Rican,” or “Cuban”) as well as those who indicate that they are “another Hispanic, Latino, or Spanish origin.” People who do not identify with one of the specific origins listed on the questionnaire but indicate that they are “another Hispanic, Latino, or Spanish origin” are those whose origins are from Spain, the Spanish-speaking countries of Central or South America, or another Spanish culture or origin. Origin can be viewed as the heritage, nationality group, lineage, or country of birth of the person or the person’s parents or ancestors before their arrival in the UnitedStates. People who identify their origin as Hispanic, Latino, or Spanish may be of any race.

The purpose of this data set is to allow exploration between various types of data that is commonly collected by the US government across the states and the USA as a whole. The data set consists of three different types of data:

• Census and Geographic Data;
• Energy Data; and
• Economic Data.

When creating the data set, I combined data from many different types of sources, all of which are cited below. I have also provided the fields included in the data set and what they represent below. I have not performed any research on the data yet, but am going to dive in soon. I am particularly interested in the relationships between various types of data (i.e. GDP or birth rate) in prediction algorithms. Given that I have compiled 5 years’ worth of data, this data set was primarily constructed with predictive algorithms in mind.

An additional note before you delve into the fields: * There could have been many more variables added across many different fields of metrics. I have stopped here, but it could potentially be beneficial to observe the interaction of these variables with others (i.e. the GDP of certain industries, the average age in a state, the male/female gender ratio, etc.) to attempt to find additional trends.

This data set shows the Tag number, Quadrat location, Species code, diameter and XY coordinates of stems >=10 cm D130 present at the time of Hurricane Hugo and in the first census. The data set is composed of two files both with the same file structure. In LFDP_C1treemap.txt the diameters (Fdiam) are as recorded in the field data. In LFDP_C1TREEMAPa.txt the stem diameters (Fdiam) were calculated to allocate "missed" stems (stems >=10 cm D130) that were found in survey 2, 3 or Census 2 to Census 1 survey 1. We calculated the diameter the stem would have had, if it had been recorded at the same time the quadrat it was located in was assessed, in the appropriate survey for that stem size. To extrapolate the stem size back in time, we used the actual growth rate of that individual stem if more than one measurement was available. If only one diameter measurement was available we used the median growth rate for that species in the appropriate size class stems >=10, <30 cm D130). In our publications we will combine data sets LFDP_C1treemap.txt and LFDP_C1TREEMAPa.txt to make Census 1 and to reconstruct the forest for stems >= 10 cm D130 at the time of Hurricane Hugo. We have divided the data into two separate files to ensure that when stem diameters are compared to future censuses the diameter data in LFDP_C1TREEMAPa.txt are not used to calculate growth rates. The last corrections to the Census 1 data were made in May 2001. The National Science Foundation requires that data from projects it funds are posted on the web two years after any data set has been organized and "cleaned". The data from each census of the LFDP will be updated at intervals as each survey of the LFDP shows errors in the previous data collection. After posting on the web, researchers who are not part of the project are then welcome to use the data. Given the enormous amount of time, effort and resources required to manage the LFDP, obtain these data, and ensure data accuracy, LFDP Principal Investigators request that researchers intending to use this data comply with the requests below. Through complying with these requests we can ensure that the data are interpreted correctly, analyses are not repeated unnecessarily, beneficial collaboration between users is promoted and the Principle Investigators investment in this project is protected. Submit to the LFDP PIs a short (1 page) description of how you intend to use the data; · Invite LFDP PIs to be co-authors on any publication that uses the data in a substantial way (some PIs may decline and other LFDP scientists may need to be included); If the LFDP PIs are not co-authors, send the PIs a draft of any paper using LFDP data, so that the PIs may comment upon it; In the methods section of any publication using LFDP data, describe that data as coming from the "Luquillo Forest Dynamics Plot, part of the Luquillo Experimental Forest Long-Term Ecological Research Program"; Acknowledge in any publication using LFDP data the "The Luquillo Experimental Forest Long-Term Ecological Research Program, supported by the U.S. National Science Foundation, the University of Puerto Rico, and the International Institute of Tropical Forestry"; · Supply the LFDP PIs with 10 reprints of any publication using LFDP data. · Accept that the LFDP PIs can not guarantee that the LFDP data you intend to use, has not already been submitted for publication or published.

EPA conducted a probabilistic survey at 64 stations from linear reef habitat along the southern coastline of Puerto Rico to characterize the regional condition of coral reef inhabitants. The probabilistic design was the first step toward establishing a long-term monitoring program for biological water quality standards (such as biocriteria) in Puerto Rico using these indicators. The target population was limited to coral reef and hardbottom substrate within 1.5 km o f shore and between 2-12 m depth. Divers dropped a buoy at the appropriate station coordinates and assessed the reef resources at the best available habitat within a 20 m radius of the buoy. If suitable habitat was not found, the next _location on the predetermined site list was chosen. This dataset is associated with the following publication: Fisher, W., D. Vivian, J. Campbell, C. Lobue, R. Hemmer, S. Wilkinson, P. Harris, D. Santavy, M. Parsons, P. Bradley, A. Humphrey, L. Oliver, and L. Harwell.

Purpose of the Caribbean Ecoregional Assessment for Puerto Rico*Puerto Rico has a well-established protected areas system safeguarding good examples of tropical ecological systems that have survived human interference. Many fine studies by professional biologists and ecologists have contributed to a solid scientific infrastructure supporting biodiversity conservation in Puerto Rico. The Nature Conservancy, whose mission is conserving the Earth's biodiversity, promotes a science-based planning process to identify a network of conservation areas with a vision to protect 10% of representative major habitat types of the world. Since the initiation of the Caribbean Ecoregional Assessment Project in 2003, the Conservancy has been gathering biodiversity and socio-economic information relevant to conservation areas design. The major goal of the Project is to design a network of landscapes and seascapes that will protect Caribbean biodiversity over the long term. Puerto Rico's rich natural diversity and solid scientific infrastructure were the reasons that the Commonwealth was chosen as a pilot study area for developing and testing nuanced methods and tools before applying them to other parts of the Project area.The general ecoregional assessment process applied to the Puerto Rican pilot study includes (1) identifying and mapping conservation targets; (2) assessing targets' ecological condition and impacts of human activities on targets; (3) setting conservation goals; (4) delineating a network of priority conservation areas; and (5) identifying gaps of biodiversity conservation in the current protected areas system-gap analysis. The purpose is to meet the following general conservation goals: protecting examples of all native ecosystem types across their environmental gradients; maintaining viable populations of all native species in natural patterns of abundance and distribution; and sustaining ecological and evolutionary processes, such as natural disturbance regimes, hydrological processes, nutrient cycles and biotic interactions. Mapping biodiversity provides the basis for conservation decision making (Richard Jeo, new info sheet, e-mail of 9/14/2004). We identified and mapped a range of coarse filter targets at the level of ecological systems using combinations of biophysical factors-climate, geology and elevation. We have also assessed the human impact on the condition of targets and mapped the relative intensity of instances of human activities.Biodiversity and socio-economic information on Puerto Rico has been collected and entered into a database that will be made freely available to interested stakeholders via the internet (with the exception of sensitive or proprietary information). The information will be organized so that new data can be easily incorporated and maintained in a central location by The Nature Conservancy. The Puerto Rico Ecoregional Assessment Project has so far gathered the following terrestrial info:. Conservation target maps- historical and current extent of areas with vegetation. Protected area maps (spatial extent and management type). Industrial agriculture maps (type and intensity). Tourism zones and a database of hotels (location and number of rooms). Urbanized areas, population density and projected population growth rate*For more detailed information, please read the CARIBBEAN ECOREGIONAL ASSESSMENT - PUERTO RICO by Shirley Keel, et al. https://conserveonline.org/docs/2005/09/PuertoRicoTerrERAMay05.pdf

Long-term longitudinal dataset with information on generational links and socioeconomic and health conditions of individuals over time. The central foci of the data are economic and demographic, with substantial detail on income sources and amounts, wealth, savings, employment, pensions, family composition changes, childbirth and marriage histories, and residential location. Over the life of the PSID, the NIA has funded supplements on wealth, health, parental health and long term care, housing, and the financial impact of illness, thus also making it possible to model retirement and residential mobility. Starting in 1999, much greater detail on specific health conditions and health care expenses is included for respondent and spouse. Other enhancements have included a question series about emotional distress (2001); the two stem questions from the Composite International Diagnostic Interview to assess symptoms of major depression (2003); a supplement on philanthropic giving and volunteering (2001-03); a question series on Internet and computer use (2003); linkage to the National Death Index with cause of death information for more than 4,000 individuals through the 1997 wave, updated for each subsequent wave; social and family history variables and GIS-linked environmental data; basic data on pension plans; event history calendar methodology to facilitate recall of employment spells (2001). The reporting unit is the family: single person living alone or sharing a household with other non-relatives; group of people related by blood, marriage, or adoption; unmarried couple living together in what appears to be a fairly permanent arrangement. Interviews were conducted annually from 1968 through 1997; biennial interviewing began in 1999. There is an oversample of Blacks (30%). Waves 1990 through 1995 included a 20% Hispanic oversample; within the Hispanic oversample, Cubans and Puerto Ricans were oversampled relative to Mexicans. All data from 1994 through 2001 are available as public release files; prior waves can be obtained in archive versions. The special files with weights for families are also available. Restricted files include the Geocode Match File with information for 1968 through 2001, the 1968-2001 Death File, and the 1991 Medicare Claims File. * Dates of Study: 1968-2003 * Study Features: Longitudinal, Minority Oversampling * Sample Size: 65,000+ Links * ICPSR Series: http://www.icpsr.umich.edu/icpsrweb/ICPSR/series/00131 * ICPSR 1968-1999: Annual Core Data: http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/07439 * ICPSR 1968-1999: Supplemental Files: http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/03202 * ICPSR 1989-1990: Latino Sample: http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/03203

The state of a population of planktic foraminifers at a certain time reflects multiple processes in the upper ocean, including environmental conditions to which the population was exposed during its growth, the age of the cohorts, and spatiotemporal patchiness. We carried out depth-stratified (0-60, 60-100 m) replicated sampling off Puerto Rico in autumn 2012, revisiting three stations previously sampled in autumn 1994 and spring 1995, in order to analyze seasonal and interannual variability of planktic foraminifers and the stable isotopic composition of their tests. The merged dataset from all three sampling campaigns allows us to assess short- and long-term changes in foraminiferal population dynamics and the spatial assemblage coherency along the shelf edge. All three sample series cover more than 2 weeks during either spring (1995) or autumn (1994, 2012) and include the time of the full moon when reproduction of some surface-dwelling planktic foraminifers has been postulated to take place. Our analyses indicate that interannual variability affected the faunal composition, and both autumn assemblages were characterized by oligotrophic tropical species, dominated by Trilobatus sacculifer and Globigerinoides ruber (white and pink variety). However, G. ruber (white) had a higher abundance in 1994 (37 %) than in 2012 (3.5 %), which may be partially due to increasing sea surface temperatures since the 1990s. Between 60 and 100 m water depth, a different faunal composition with a specific stable oxygen isotope signature provides evidence for the presence of the Subtropical Underwater at the sampling site. Measurements on T. sacculifer sampled in autumn 2012 revealed that test size, calcification and incidence of sac-like chambers continued to increase after full moon, and thus no relation to the synodic lunar reproduction cycle was recognized. During autumn 2012, outer bands of hurricane Sandy passed the Greater Antilles and likely affected the foraminifers. Lower standing stocks of living planktic foraminifers and lower stable carbon isotope values from individuals collected in the mixed layer likely indicate the response to increased rainfall and turbidity in the wake of the hurricane.

Hurricane Hugo struck the Caribbean national forest in September 1989. Files LFDP_HURRDAM.TXT and LFDP_HURRDAMa.TXT contain data on the damage to trees caused by the hurricane collected by Mr. R. DeLeon between August 1990 and September 1991. Mr. DeLeon walked throughout the plot to find stems >= 10 cm diameter that had apparently been damaged or killed by the hurricane in an effort to collect information before the damaged stems rotted. The information on these stems was later combined with the results of the first census to reconstruct the forest, as it would have appeared, at the time of Hurricane Hugo. This file contains the hurricane damage data collected for stems damaged by Hurricane Hugo combined with data for the stems recorded subsequently in the first complete LFDP census starting in 1990. Some stems that were measured in Census 1 survey 2 and survey 3 or Census 2 that were believed to have been missed in Census 1 survey 1, are also included (see census history above) and are assumed to have been undamaged by Hurricane Hugo. The structure of the data files is the same for both files LFDP_HURRDAM.TXT and LFDP_HURRDAMa.TXT but the diameter of the trees in LFDP_HURRDAMa.TXT have been calculated by extrapolating diameters backwards from subsequent measurements to the time of the Census 1 survey 1. Diameters in file LFDP_HURRDAMa.TXT can not be used for growth measurements. For our publications we treat files LFDP_HURRDAM.TXT and LFDP_HURRDAMa.TXT as one data set. The National Science Foundation requires that data from projects it funds are posted on the web two years after any data set has been organized and "cleaned". The data from each census of the LFDP will be updated at intervals as each survey of the LFDP shows errors in the previous data collection. After posting on the web, researchers who are not part of the project are then welcome to use the data. Given the enormous amount of time, effort and resources required to manage the LFDP, obtain these data, and ensure data accuracy, LFDP Principal Investigators request that researchers intending to use this data comply with the requests below. Through complying with these requests we can ensure that the data are interpreted correctly, analyses are not repeated unnecessarily, beneficial collaboration between users is promoted and the Principle Investigators investment in this project is protected. Submit to the LFDP PIs a short (1 page) description of how you intend to use the data; · Invite LFDP PIs to be co-authors on any publication that uses the data in a substantial way (some PIs may decline and other LFDP scientists may need to be included); If the LFDP PIs are not co-authors, send the PIs a draft of any paper using LFDP data, so that the PIs may comment upon it; In the methods section of any publication using LFDP data, describe that data as coming from the "Luquillo Forest Dynamics Plot, part of the Luquillo Experimental Forest Long-Term Ecological Research Program"; Acknowledge in any publication using LFDP data the "The Luquillo Experimental Forest Long-Term Ecological Research Program, supported by the U.S. National Science Foundation, the University of Puerto Rico, and the International Institute of Tropical Forestry"; · Supply the LFDP PIs with 10 reprints of any publication using LFDP data. · Accept that the LFDP PIs can not guarantee that the LFDP data you intend to use, has not already been submitted for publication or published.

The Public Libraries Survey (PLS) provides statistics on the status of public libraries in the United States. It is a voluntary survey conducted annually by the Institute of Museum and Library Services (IMLS). The Fiscal Year (FY) 2014 survey is the 26th in the series. The data files include all public libraries identified by state library administrative agencies in the 50 States, the District of Columbia, and the outlying areas of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands. The reporting unit for the survey is the administrative entity, defined as the agency that is legally established under local or state law to provide public library service to the population of a local jurisdiction. In this survey, the term public library means an administrative entity. For Fiscal Year 2014, IMLS collected the following information via a web-based survey for the PLS: Library Data - Data on each public library, such as its name and address, population of legal service area, service outlets, collections, full-time-equivalent staff, and operating revenue and expenditures. State characteristics data, including the reporting period starting and ending dates, the state total population estimate, and the total unduplicated population of legal service areas for the state. These data are contained in dataset 1 and include 9,305 records; 9,295 were public libraries and 10 were administrative entities that closed or temporarily closed for FY 2014. State Data - Each state library agency reported these data on the "State Characteristics" record because they are not library-level data. These data are in dataset 2 and include 56 records, one for each state and outlying area. Outlet Data - Data on each public library service outlet, such as its name and address, type, county location, metropolitan status, square footage, public service hours per year, and number of weeks a library outlet is open. These data are in dataset 3 and include 17,566 total records, 17,492 are public library service outlets (central, branch, bookmobile, and books-by-mail-only outlets). The remaining 74 records are outlets that closed or temporarily closed for FY 2014. This data collection is useful to researchers, journalists, the public, and policymakers at the federal, state, and local levels. These data are used by federal, state and local officials, professional associations, and local practitioners for planning, evaluation, and policy making.
