I don't buy into this "research" that for all purposes is a copy and paste of American literature and substitute of Kenya for USA. USA is very capitalist, individualistic, polygamy/bigamy is a crime, divorce is taken casually. Kenyan marriages are deeply entrenched in community and the church. Divorce is stigmatized, polygamy / MWK tolerated.
Divorce rates in USA as high as 18 per 1000 couples. 200 divorces in Nairobi barely significant to establish correlation.
Many people in USA are on hourly/piece meal rates so recession hits hard. Most Kenyans are state employees or subsistence farmers, recession hardly registers.
The writer has not done scientific research to establish correlation between divorce and economic conditions in Kenya neither cited any.
Life is short. Live passionately.
