Wavelet coherence between A, population and yield; C, population and price; E, population and CPI; and G, population and real wage is computed in the to year band. The most consistent and continuous coherent region red color in the core area occurs in the band of 40 years and above.
First, a consistent and continuous frequency band of 60—80 years was observed, as shown in Fig 2. They are the three many widespread types of contemporary society. The value of the blue-collar employee declines, because the value of experienced professionals boosts.
The dotted line represents phase difference; the red line represents the phase of population; and the blue line represents the phase of the corresponding variable. Preindustrial societies are primarily agricultural, and because of this there is little variation of social classes.
Hence, identifying the structure of an agrarian economy in the past can help us understand the economic fluctuations during the study period. However, a year low-pass filter is still retained for population and four other indicators.
In postindustrial communities the focus adjustments from mass production to technological innovation. Agricultural based societies were replaced with industrial societies which were based on the use of machines to produce goods.
Third, after closely inspecting the results of the spectrum analysis of the seventeenth century, a short frequency band in temperature of around 20 years 15—35 years is observed. There are many types of societies, but three of the most prevalent types are the preindustrial, industrial, and postindustrial.
