"The Federal Bureau of Prisons (BOP) is a United States federal law enforcement agency. A subdivision of the U.S. Department of Justice, the Bureau is responsible for the administration of the federal prison system. The system also handles prisoners who committed acts considered felonies under the District of Columbia's law. The Bureau was established in 1930 to provide more progressive and humane care for federal inmates, to professionalize the prison service, and to ensure consistent and centralized administration of the 11 federal prisons in operation at the time.
According to its official web site, the Bureau consists of more than 116 institutions, six regional offices, its headquarters office in Washington, D.C., two staff training centers, and 22 community corrections offices, and is responsible for the custody and care of approximately 210,000 federal offenders. Approximately 82 percent of these inmates are confined in Bureau-operated correctional facilities or detention centers. The remainder are confined through agreements with state and local governments or through contracts with privately operated community corrections centers, detention centers, prisons, and juvenile facilities."

"A time series is a sequence of data points, measured typically at successive points in time spaced at uniform time intervals. ... Time series are very frequently plotted via line charts. Time series are used in statistics, signal processing, pattern recognition, econometrics, mathematical finance, weather forecasting, earthquake prediction, electroencephalography, control engineering, astronomy, and communications engineering. Time series analysis comprises methods for analyzing time series data in order to extract meaningful statistics and other characteristics of the data. Time series forecasting is the use of a model to predict future values based on previously observed values. While regression analysis is often employed in such a way as to test theories that the current values of one or more independent time series affect the current value of another time series, this type of analysis of time series is not called "time series analysis", which focuses on comparing values of time series at different points in time. Time series data have a natural temporal ordering." [Time series. Wikipedia]
