Panel de vida
El Panel de Probabilidad online de nueva generación en Europa
Lifepanel se fundó con la misión de proporcionar a la industria de la investigación acceso a un panel de probabilidad online independiente con rigor metodológico.
Países cubiertos
Mil. Encuestados basados en probabilidades
Conocimientos científicos sobre Europea hogares
Estamos construyendo Lifepanel a partir de décadas de experiencia en investigación social y política, y junto con socios clave, que han verificado cada paso del proceso de muestreo.
Enfoque europeo
País Cobertura
Los encuestados del panel se obtienen de los marcos de telefonía fija y móvil de los marcos telefónicos nacionales de los países europeos. Dado que el acceso a Internet y al teléfono alcanza una cobertura casi total en la mayoría de los países europeos, disponemos de una muestra bastante representativa de la población europea.
Certificaciones
Reconocida a nivel mundial investigación normas
Una recertificación anual de las normas ISO 27001, ISO 20252, en combinación con una documentación específica sobre políticas, metodologías de muestreo y estructura de calidad, garantiza la calidad del muestreo a nivel empresarial.

Panel cerrado
Lifepanel es un panel estricto sólo para invitados
Cada número de teléfono está vinculado a un identificador único que actúa como contraseña. Esto impide que las personas se registren por sí mismas.
Datos reales
Resultados transparentes más allá de los datos de la encuesta
Proporcionamos un desglose completo de los índices de respuesta, los datos demográficos de los completos, el número total de miembros del panel invitados, los resultados ponderados y no ponderados, y las probabilidades de selección de cada encuestado.

Most recent studies showcase that full probability samples provide the most precise data. Studies that utilize a probability sample combined with an opt-in sample are less accurate than studies that make use of full probability samples. Least accurate are surveys comprised entirely of opt-in panel sample*.
Lifepanel is a fully probability-based panel since it recruits randomly selected panelists from a probability based sample source that reflects the population of 16 and over of a given country (Single or Dual-Frame RDD).
The data obtained from this panel can statistically represent the target population with a known margin of error. Lifepanel is a strict invite-only panel and does not allow standalone volunteering or referrals to be part of Lifepanel. All respondents must be selected randomly, invited and verified by phone to participate.

The Lifepanel is weighted to be representative of the entire residential adult population of a specific country. The first step in the weighting process is the application of a base weight that accounts for the DFRDD (or single mobile frame) sample design and the within-household sampling of one respondent aged 16 and over.
Following the base weight, the panel is calibrated to correct for differential participation along demographics such as age, urbanicity, gender, region, employment status and education. Benchmark distributions are obtained from the most recently available data, Eurostats, and dedicated national registers.
Final weights for the Lifepanel survey data reflect individual respondents’ probability of selection into the sample and are again calibrated to country benchmarks to ensure that Lifepanel survey data accurately represent the opinions of a given country.
We provide several files with every delivery:
- Clean and weighted data available in a variety of formats (e.g. Excel, SPSS, .csv etc.)
- Additional outputs to meet your needs: from analysis tables and significance testing to complex multi-variate regressions analysis and segmentations; from slide-decks to detailed reports
- Weighted crosstabs with standard demographics
- Weighted SPSS data file with standard demographic variables from the survey or panelist profile data (also available in Excel, CSV, or SAS)
- Methods report
Since the respondents are recruited via phone, it represents the entire population with access to phone aged 16 and over of a given country.
The majority of the panel members are invited to surveys via SMS, Email and WhatsApp while a small percentage is interviewed via phone to ensure the non-online part of the population is covered as well.
