SPDkurvor

SPDkurvor is a German-language term that denotes a time-series curve showing the level of support for the Social Democratic Party of Germany (SPD) over time, typically presented in political reporting, polling analyses, and election forecasting. The curve aggregates data points from public opinion polls or election results and is plotted with time on the horizontal axis and support percentage or seat share on the vertical axis. It is used to visualize trends, compare the SPD against other parties, and illustrate momentum before elections.

Construction often involves collecting polling data from multiple institutes, aligning dates, and applying smoothing or aggregation, such as a poll-of-polls, moving averages, or LOESS smoothing. Uncertainty is usually represented by error bars or shaded confidence bands. Analysts interpret SPDkurvor in light of methodological differences between pollsters, changes in turnout, and significant political events.

Context and variants: While rooted in German-language media, the concept is comparable to time-series curves for any political party. The exact presentation can vary, including daily updates, weekly composites, or event-driven spikes around campaigns.

Etymology: "SPD" stands for Sozialdemokratische Partei Deutschlands, and "Kurvor" is German for curve.
