There are patterns in causes of deaths of U.S. people. I plotted the data as individual states with death rates along years and causes of deaths (c.o.d.) variables. Three layers are visible in these graphs. By far the most frequently occuring c.o.d. are heart disease and cancer which constitute the top layer. C.o.d. in the middle layer are moderately frequent. The middle layer comprises various diseases. The most commonly found c.o.d. in there are diseases of the respiratory, digestive, or nervous system, and external causes. The bottom layers comprises c.o.d. that are relatively rare. When plotted in single c.o.d., death rates of several c.o.d. show well-defined curved trends, suggesting their predictability potential.

Keyword occurence patterns vary between countries. In all countries, the keywords occured sparsely. Some countries have more continuous patterns than others. Trending topics can be authentic, i.e. formed by natural conversations, or inauthentic, i.e. formed by bots or political campaign teams. Thus far, the trending topics patterns didn’t seem to reflect the authenticity of the conversations.
