# Costa Rican Household Poverty Level Prediction — Data 来源：https://www.kaggle.com/competitions/costa-rican-household-poverty-prediction/data 采集时间：2026-10-20T01:32:10Z ## File descriptions * **{train|test}.csv** - the training set - This is the main table, broken into two files for Train (with a Target column) and Test (without the Target column). - One row represents one person in our data sample. - Multiple people can be part of a single household. Only predictions for heads of household are scored. * **sample_submission.csv** - a sample submission file in the correct format - This file contains all test IDs and a default value. - **Note** that ONLY the heads of household are used in scoring. All household members are included in test + the sample submission, but only heads of households are scored. ## Core Data fields * **Id** - a unique identifier for each row. * **Target** - the target is an ordinal variable indicating groups of income levels. 1 = extreme poverty 2 = moderate poverty 3 = vulnerable households 4 = non vulnerable households * **idhogar** - this is a unique identifier for each household. This can be used to create household-wide features, etc. All rows in a given household will have a matching value for this identifier. * **parentesco1** - indicates if this person is the head of the household. * This data contains 142 total columns. ## All Data fields **Variable name, Variable description** v2a1, Monthly rent payment hacdor, =1 Overcrowding by bedrooms rooms, number of all rooms in the house hacapo, =1 Overcrowding by rooms v14a, =1 has bathroom in the household refrig, =1 if the household has refrigerator v18q, owns a tablet v18q1, number of tablets household owns r4h1, Males younger than 12 years of age r4h2, Males 12 years of age and older r4h3, Total males in the household r4m1, Females younger than 12 years of age r4m2, Females 12 years of age and older r4m3, Total females in the household r4t1, persons younger than 12 years of age r4t2, persons 12 years of age and older r4t3, Total persons in the household tamhog, size of the household tamviv, number of persons living in the household escolari, years of schooling rez_esc, Years behind in school hhsize, household size paredblolad, =1 if predominant material on the outside wall is block or brick paredzocalo, "=1 if predominant material on the outside wall is socket (wood, zinc or absbesto" paredpreb, =1 if predominant material on the outside wall is prefabricated or cement pareddes, =1 if predominant material on the outside wall is waste material paredmad, =1 if predominant material on the outside wall is wood paredzinc, =1 if predominant material on the outside wall is zink paredfibras, =1 if predominant material on the outside wall is natural fibers paredother, =1 if predominant material on the outside wall is other pisomoscer, "=1 if predominant material on the floor is mosaic, ceramic, terrazo" pisocemento, =1 if predominant material on the floor is cement pisoother, =1 if predominant material on the floor is other pisonatur, =1 if predominant material on the floor is natural material pisonotiene, =1 if no floor at the household pisomadera, =1 if predominant material on the floor is wood techozinc, =1 if predominant material on the roof is metal foil or zink techoentrepiso, "=1 if predominant material on the roof is fiber cement, mezzanine " techocane, =1 if predominant material on the roof is natural fibers techootro, =1 if predominant material on the roof is other cielorazo, =1 if the house has ceiling abastaguadentro, =1 if water provision inside the dwelling abastaguafuera, =1 if water provision outside the dwelling abastaguano, =1 if no water provision public, "=1 electricity from CNFL, ICE, ESPH/JASEC" planpri, =1 electricity from private plant noelec, =1 no electricity in the dwelling coopele, =1 electricity from cooperative sanitario1, =1 no toilet in the dwelling sanitario2, =1 toilet connected to sewer or cesspool sanitario3, =1 toilet connected to septic tank sanitario5, =1 toilet connected to black hole or letrine sanitario6, =1 toilet connected to other system energcocinar1, =1 no main source of energy used for cooking (no kitchen) energcocinar2, =1 main source of energy used for cooking electricity energcocinar3, =1 main source of energy used for cooking gas energcocinar4, =1 main source of energy used for cooking wood charcoal elimbasu1, =1 if rubbish disposal mainly by tanker truck elimbasu2, =1 if rubbish disposal mainly by botan hollow or buried elimbasu3, =1 if rubbish disposal mainly by burning elimbasu4, =1 if rubbish disposal mainly by throwing in an unoccupied space elimbasu5, "=1 if rubbish disposal mainly by throwing in river, creek or sea" elimbasu6, =1 if rubbish disposal mainly other epared1, =1 if walls are bad epared2, =1 if walls are regular epared3, =1 if walls are good etecho1, =1 if roof are bad etecho2, =1 if roof are regular etecho3, =1 if roof are good eviv1, =1 if floor are bad eviv2, =1 if floor are regular eviv3, =1 if floor are good dis, =1 if disable person male, =1 if male female, =1 if female estadocivil1, =1 if less than 10 years old estadocivil2, =1 if free or coupled uunion estadocivil3, =1 if married estadocivil4, =1 if divorced estadocivil5, =1 if separated estadocivil6, =1 if widow/er estadocivil7, =1 if single parentesco1, =1 if household head parentesco2, =1 if spouse/partner parentesco3, =1 if son/doughter parentesco4, =1 if stepson/doughter parentesco5, =1 if son/doughter in law parentesco6, =1 if grandson/doughter parentesco7, =1 if mother/father parentesco8, =1 if father/mother in law parentesco9, =1 if brother/sister parentesco10, =1 if brother/sister in law parentesco11, =1 if other family member parentesco12, =1 if other non family member idhogar, Household level identifier hogar_nin, Number of children 0 to 19 in household hogar_adul, Number of adults in household hogar_mayor, #
